Answer:
Explanation:
We would most likely write the velocity of the ball as follow :
V(b<em>all</em> with respect to t<em>rain)</em> = Vbt
To solve this problem we will apply the concepts related to the conservation of momentum. This can be defined as the product between the mass and the velocity of each object, and by conservation it will be understood that the amount of the initial momentum is equal to the amount of the final momentum. By the law of conservation of momentum,

Here,
= Mass of Basketball
= Mass of Tennis ball
= Initial velocity of Basketball
= Initial Velocity of Tennis ball
= Final velocity of Basketball
= Final velocity of the tennis ball
Replacing,

Solving for the final velocity of the tennis ball

Therefore the velocity of the tennis ball after collision is 11 m/s
For the object to be moving, there must be a value for the forces acting on this object in a certain direction to cause the object to move.
On the other hand, when an object is at rest, despite the possibility of having several forces acting on it, these forces balance out to a net force of zero which keeps the body still with no motion.
