Answer:
Explanation:
The magnitude of the change in momentum of block A is <u>equal and opposite </u>the magnitude of the change in momentum of block B.
According to law of conservation of momentum , there should not be any change in the momentum in the system .The system consists of A and B . So if some change in momentum has occurred in A , the other must have equal and opposite change in momentum so that they get cancel out and net change in momentum of system is zero.
A. The potential energy is always the highest at the top and the kinetic energy is always the lowest at the top.

The friend who has the greater displacement is the one who takes the longest path.
<h3>What is displacement?</h3>
The displacement is the shortest distance travelled by the particle. It is the vector quantity which re[presents both the magnitude and direction.
Given, two friends leave a movie theater and take different buses to the same ice cream shop. One bus takes a longer route driving on a high-speed highway, while the other takes a shorter route on lower-speed local roads.
According to the definition. the displacement is neither larger not shorter but it is the shortest distance traveled by the person or particle.
Thus, friend who has longer path has larger displacement.
