When a small cart collide with a large mass then during collision they must be in contact with each other for some interval of time
During this contact interval we can say they will exert normal force on each other
This normal force is always equal and opposite on two balls which means this force will follow Newton's III law
It will be same in magnitude but opposite in the direction
So here correct answer would be
<u><em>They both experience the same magnitude of the collision force.</em></u>

<u>KINETIC ENERGY</u></h2>
<h3>Problem:</h3>
» Kinetic energy of 35 J and a mass of 34 kg, how fast is the object moving?
<h3>Answer:</h3>
— — — — — — — — — —
<h3>Formula:</h3>
To calculate the velocity of a kinetic energy, we can use formula
where,
- v is the velocity in m/s
- KE is the kinetic energy in J (joules)
- m is the mass in kg
Based on the problem, the givens are:
- KE (Kinetic energy) = 35 J
- m (mass) = 34 kg
- v (velocity) = ? (unknown)
<h3>Solution:</h3>
To get the velocity, substitute the givens in the formula above then solve.
Therefore, the velocity is 1.435 m/s.
Answer:
4
Explanation:
Given parameters:
Force input = 30N
Force output = 120N
Unknown:
Mechanical advantage of the lever = ?
Solution:
The mechanical advantage is the quantity that describes how much a simple machine is able to multiply force.
This is expressed as:
Mechanical advantage = Force output / Force input
Mechanical advantage = = 4
Your answer is D it is accelerating forward
