A bicycle will move backward.A car will move in the same direction.A ball will have sideways due to unbalanced force.What is Unbalanced Force?Unbalanced force is defined as the forces which are not equal in magnitude. When two forces with different magnitudes are applied on an object from opposite directions, the object will start moving in the direction of the net force.
These forces result in the motion of an object.
Balanced forces are the forces which are equal in magnitude. When two forces with equal magnitude are applied on an object from opposite directions, the object will not start moving.
These forces does not result in the motion of an object.
Hence, this force will cause the motion in an object.

A 4.0 kg dog runs from one end of a 21 kg canoe to the other, a distance of 4.9 m. Assuming negligible water resistance, how far does the canoe move in metres?
The distance traveled by the canoe in the water is 0.93 m.
The given parameters;
mass of the dog, m = 4.0 kgmass of the canoe, = 21 kgdistance traveled by the dog, d = 4.9 mApply the principle of conservation of linear momentum to determine the distance traveled by the canoe;
[tex]m_1v_1 = m_2 v_2\\\\m_1(\frac{d_1}{t} ) = m_2(\frac{d_2}{t} )\\\\4(4.9) = 21(d_2)\\\\d_2 = \frac{4(4.9)}{21} \\\\d_2 = 0.93 \ m[/tex]
Thus, the distance traveled by the canoe in the water is 0.93 m.

A small insect smashes into the windshield of your car while you are zooming down the interstate. Which exerts the larger force; the bug on the car or the car on the bug?
Force is directly proportional to the mass of the body. The small insects weight so small thus the force exerted by the insect will be smaller. Thus the force exerted by the car is greater.
What is force?Force is an external agent acts on a body to change it from the state of rest or motion. Various kinds of forces include magnetic force, frictional force, nuclear force, gravitational force etc.
In physics, force is the product of mass and the acceleration. Thus force has the expression F = ma. Therefore, the force exerted from a massive body is greater than the force exerted from a lighter body.
The car is very large in comparison to the insect and it weighs a lot where, the weight of the insect and the force exerted by it is negligible. Hence, the force exerted by the massive body that is car is larger than that by the small insect.

I NEED ANSWERS ASAP!!!! Which of the following would accelerate faster with the same amount of force?
150 pound person on a skateboard
200 pound person on a skateboard
They all accelerate equally
300 pound person on a skateboard
150 pound person on a skateboard
The 150-pound person on a skateboard would accelerate faster with the same amount of force. Therefore, option (A) is correct.
What is acceleration?Acceleration of a body is demonstrated as the change of velocity with respect to time. The acceleration is a vector parameter as it carries both magnitude and direction. Acceleration is defined as the 2nd derivative of position w.r.t. time and the 1st derivative of velocity w.r.t. time.
According to Newton's 2nd law, the force is equal to the multiplication of the mass and acceleration of an object.
F = ma
and, a ∝ 1/m
From the above equation, we can say that acceleration (a) is inversely proportional to the mass (m) of the body.
In the given option the person with a mass of 150 pounds will accelerate faster with the same amount of force and the person with a mass of 300 pounds will accelerate the least.
