a load of 600 kg is lifted by a carne up to 60 meters in 6 minutes . calculate it work and power.
Explanation:
work=force*distance. force=load/10
___________
work=60*60=3600n
power=work/time(seconds)
Powe required is 1000
Explanation:
-Given: M= 600kg H: 60
-Time of operation: t = 6 min = 360 seconds
-Work done in lifting boxes: w= mgh (600 x 10 x 60) = 360,000
-Power required: p=[tex]\frac{w}{t} = \frac{360000}{360} = 1000[/tex]

El Burj Khalifa es la torre más alta de Dubai y mide 821 m. Si se deja caer una moneda desde lo alto de la torre, ¿cuál es la magnitud de la velocidad con la que choca con el suelo?
Answer:
Vf = 126,85 m/s
Explanation:
En este caso, vamos a asumir que la velocidad inicial de la moneda cuando se deja caer es cero, puesto que no nos lo indican. Al ser la velocidad inicial cero, lo unico que influye en la velocidad de la moneda es la gravedad y la altura, por ende, la siguiente formula nos ayudará a calcularla:
Vf² = Vo² - 2gh (1)
Pero como la velocidad inicial es cero, y si también asumimos que la dirección de bajada será nuestro eje positivo, entonces:
Vf² = 2gh (2)
Ahora solo nos queda, reemplazar los valores de altura que es 821 m, y la aceleración de gravedad que es 9.8 m/s² y resolvemos la velocidad:
Vf² = 2 * 9,8 * 821
Vf = √16091,6
Vf = 126,85 m/sEsta debería ser la velocidad con que llega al suelo.
Exitos
La magnitud de la velocidad con la que choca con el suelo es aproximadamente 126.898 metros por segundo.
Si despreciamos los efectos de la viscosidad del aire y la aceleración de Coriolis, entonces el movimiento de la moneda se describe por el movimiento de caída libre, es decir, un movimiento uniforme acelerado debido a la gravedad terrestre. La velocidad final de la moneda es determinada por la siguiente ecuación cinemática:
[tex]v = \sqrt{v_{o}^{2}+2\cdot a\cdot h}[/tex] (1)
Donde:
[tex]v_{o}[/tex] - Velocidad inicial, en metros por segundo.[tex]a[/tex] - Aceleración, en metros por segundo al cuadrado.[tex]h[/tex] - Altura, en metros.[tex]v[/tex] - Velocidad final, en metros por segundo.Si sabemos que [tex]v_{o} = 0\,\frac{m}{s}[/tex], [tex]a = 9.807\,\frac{m}{s^{2}}[/tex] y [tex]h = 821\,m[/tex], entonces la velocidad final de la moneda es:
[tex]v = \sqrt{\left(0\,\frac{m}{s} \right)^{2}+2\cdot \left(9.807\,\frac{m}{s^{2}} \right)\cdot (821\,m)}[/tex]
[tex]v\approx 126.898\,\frac{m}{s}[/tex]
La magnitud de la velocidad con la que choca con el suelo es aproximadamente 126.898 metros por segundo.

How can you use the period of a wave to find the frequency?
Explanation:
Frequency is the number of occurrences of a repeating event per unit of time.
It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency.
The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
Relationship between Period and frequency is as under :
The frequency of a wave describes the number of complete cycles which are completed during a given period of time.
As such, frequency is a rate quantity which describes the rate of oscillations or vibrations or cycles or waves on a per second basis.
A common unit of frequency is the Hertz, abbreviated as Hz.
Frequency
=
1
Period
f = c / λ = wave speed c (m/s) / wavelength λ (m).

Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N What is the acceleration of his fall?
Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N. The acceleration of his fall 7.5 m/sec².
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
To find the acceleration,
F = mg
F = 80.(10)
F = 800 N
air resistance = 200 N
Net force = F - air resistance
= 800 - 200
= 600 N
600 = mass . acceleration
600 = 80 . acceleration
acceleration = 7.5 m/sec²
Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N. The acceleration of his fall 7.5 m/sec².

An 12 kg object accelerating from 9 m/s to 14 m/s. What is the change in momentum of the object?
Answer:
Change in momentum = 60kgm/s.
Explanation:
Given the following data;
Mass, m = 12kg
Initial velocity, u = 9m/s
Final velocity, v = 14m/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
[tex] Momentum = mass * velocity [/tex]
To find the change in momentum;
Mathematically, change in momentum is given by the formula
[tex] Change \; in \; momentum = m(v - u) [/tex]
Substituting into the equation, we have;
[tex] Change \; in \; momentum = 12(14 - 9) [/tex]
[tex] Change \; in \; momentum = 12*5[/tex]
Change in momentum = 60kgm/s.

MARK ME AS BRAINLISTA box of books weighing 315 N is shoved across the floor by a force of 477 N exerted downward at an angle of 35° below the horizontal. If the coefficient of kinetic friction between the box and the floor is 0.58, how long does it take to move the box 4.20 m starting from rest?
Answer:
It takes 1.14 s to move the box 4.20 m.
Explanation:
Using Newton's second law we have:
[tex]Fcos(35)-F_{f}=ma[/tex]
[tex]Fcos(35)-\mu mg=ma[/tex]
F is the force exerted and m the mass of the books
[tex]Fcos(35)-\mu mg=ma[/tex]
[tex]477cos(35)-(0.58*315)=\frac{315}{9.81}a[/tex]
So, the books accelerate at:
[tex]a=6.48\: m/s^{2}[/tex]
We know that the initial velocity is zero, so using the kinematic position equation, we have:
[tex]x=\frac{1}{2}at^{2}[/tex]
So, we just need to solve the equation for t.
[tex]4.2=\frac{1}{2}6.48t^{2}[/tex]
[tex]t=\sqrt{\frac{2*4.2}{6.48}}[/tex]
Taking the positive value of t:
[tex]t=1.14\: s[/tex]
Therefore, it takes 1.14 s to move the box 4.20 m.

The power generated by the engine was just 2.984 KW. How long would this engine have to run to produce 3.60 × 104 J of work?
1 watt = 1 joule/second
1 KW = 1,000 joule/second
Work = (power) x (time)
3.6 x 10⁴ J = (2,984 joules/second) x (time)
time = (3.6 x 10⁴J) / (2,984 J/s)
time = (36,000J) / (2,984 J/s)
time = 12.06 seconds
