Dominique and her sister are practicing their basketball skills at the park. If both Dominique and her sister both throw their basketballs at the same time and they hit each other. What would happen to their basketballs? a) Only the basketball's speed would be changed b) Only the basketball's directions would be changed c) Both the basketball's speed and direction would change d) Neither the basketball's speed nor direction would change

Option C, Both the basketball's speed and direction would change

Explanation:

When two objects travelling with certain speed interact with each their internal forces changes and hence their motion changes simultaneously.

In general cases it is said that momentum is conserved. Momentum is nothing but just the product of mass and velocity.

As the motion of the football changes, then momentum also changes. Since mass is a constant value, it is the velocity of the football that changes.

Hence, both speed and direction of both the football changes.
