Answer:

6 m/s East

Explanation:

Momentum = Mass . Velocity

26100 = 4350. Velocity

Velocity = 6m/s East

Answer:

[tex]\boxed {\boxed {\sf 2 \ m/s^2}}[/tex]

Explanation:

Acceleration can be found by dividing the change in velocity by the time.

[tex]a=\frac{\Delta v}{t}[/tex]

The time is 1.25 seconds.  The change in velocity is the difference between the initial velocity and the final velocity.

[tex]\Delta v= 2.5 \ m/s\\t=1.25 \ s[/tex]

Substitute the values into the formula.

[tex]a=\frac{2.5 \ m/s}{1.25 \ s}[/tex]

Divide.

[tex]a=2 \ m/s^2[/tex]

The sprinter's average acceleration is 2 meters per second squared.

Answer: 2 m/s^2

Answer:

between 0s and 0.5s

Explanation:

the objects position is moving away from the origin and the position-versus-time curve has a positive slope

Answer:

a. same

b. less

c. less

Explanation:

you can use the position, time, acceleration equation

xf=xi + vi*t+(at^2)/2

you can say the final distance will greater for X than Y

using acceleration for gravity a=9.81m/s^2

a.  both X and Y will have the same acceleration due to gravity

b. to solve for final speed vf=vi+gt

since the initial velocity is 0 and X will take longer to fall, Y will hit the ground with less speed

c. as mentioned before, X will take longer to fall; therefore Y will have less time of descent.

Answer:

42secs

Explanation:

v=u-gt

0=7-10t

10t=7

t=7/10

t=7/10*60

t=42

Answer:

Divide by the number 100

Explanation:

Since there are 100 centimeters in 1 meter, we can see that if you are given a number in centimeters, the number of meters is that number divided by 100. Hope this helps!

Answer:

Divide by 100

Explanation:

[tex]g = \frac{GMm}{r^2}[/tex]

where [tex]G[/tex] is the gravitational constant and is about [tex]6.67 * 10^{-11}[/tex]

[tex]g = \frac{6.67 * 10^{-11} * 25 * 0.55}{35^2}[/tex]

[tex]g = \frac{6.67 * 10^{-11} * 25 * 0.55}{1225} = 0.000000000000749 N[/tex] :D

Answer:

Acceleration, a = 750m/s²

Explanation:

Given the following data;

Radius, r = 0.31m

Velocity, v = 15m/s

To find the centripetal acceleration;

[tex] Acceleration, a = \frac {v^{2}}{r}[/tex]

Substituting into the equation, we have;

[tex] Acceleration, a = \frac {15^{2}}{0.31}[/tex]

[tex] Acceleration, a = \frac {225}{0.31}[/tex]

Acceleration, a = 750m/s²

Therefore, the centripetal acceleration of the bike wheel is 750m/s².

Answer:

The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve.

Explanation:LET ME KNOW IF ITS WRONG. HAVE A NICE DAY!!!!!!!!!!

Answer: The net force on a car traveling around a curve is the centripetal force, Fc = m v2 / r, directed toward the center of the curve. The centripetal force is directed at right angles to the motion and also along the radius towards the centre of the circular path. In order for a car to move around a circular track, something must provide a centipetal force. One source of the centripetal force is friction between the tires and the road. This means that the tires do not need to supply any friction at all to keep the car from slipping sideways. ...

Hope this helps... stay safe and have a great day!!! :D

Answer:

the total work done is 90J

Explanation:

the reason why is because you are the force (30 newtons) and the metere (3) so you will be multiplying those two numbers together.

W= FD 30(3)= 90J

Answer:

8000cm³/hr

Explanation:

Given parameters:

Volume of the liquid draining off per hour   = 8000cm³

Time taken to drain off  = 1hr

Unknown:

Flow rate  = ?

Solution:

Flow rate is the volume of fluid that passes per unit of time.

 Flow rate  = [tex]\frac{volume of fluid}{time taken}[/tex]  

 Flow rate  = [tex]\frac{8000cm^{3} }{1hr}[/tex]  

Flow rate  = 8000cm³/hr

An ammeter is used to measure current.

Answer:

Fnet = 13.86N

Explanation:

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

Mathematically, net force is given by the formula;

[tex] Fnet = Fapp + Fg[/tex]

Where;

Given the following data;

Mass = 1.1kg

Acceleration = 2.8m/s²

To find the applied force;

[tex] Fapp = ma[/tex]

Substituting into the equation, we have;

[tex] Fapp = 1.1 * 2.8[/tex]

Fapp = 3.08N

To find the gravitational force;

We know that acceleration due to gravity, g = 9.8m/s²

[tex] Fg = mg[/tex]

Substituting into the equation;

[tex] Fg = 1.1 * 9.8[/tex]

Fg = 10.78N

To find the net force;

[tex] Fnet = Fapp + Fg[/tex]

Substituting into the equation, we have;

[tex] Fnet = 3.08 + 10.78[/tex]

Fnet = 13.86N

Therefore, the net force required is 13.86N

Answer:

Explanation:

A scenario in which an authoritarian leadership would be beneficial is in law enforcement in emergency cases (that has to do with public safety or national security) without the bureaucratic bottlenecks of the legislature and judiciary. For example, the recent coronavirus pandemic, authoritarian leaderships would find it easier to enforce the laws on wearing of masks and also prevent producers of personal protective equipment (PPE) from unreasonably inflating prices of there PPEs.

As explained above, it would work well because there will be no legislative bottleneck that will start a hearing at the expense of public safety neither will there be a court that will stall the process at the same expense.

The risks here is that businesses (in this case that of producing PPEs) may find it difficult to survive since the "tone" of the pricing of PPEs will now be determined by government. It may even hinder healthy business competition. It may also lead to production of substandard PPEs in order to generate enough profit (since the main aim of any business is to generate profit).
