Question

First, let us consider an object launched vertically upward with an initial speed v. Neglect air resistance. Part B) At the top point of the flight, what can be said about the projectile's kinetic and potential energy?

A). Both kinetic and potential energy are at their maximum values.
B).Both kinetic and potential energy are at their minimum values.
C).Kinetic energy is at a maximum; potential energy is at a minimum.
D).Kinetic energy is at a minimum; potential energy is at a maximum.

Answer 1

Option d is the correct option Kinetic energy is minimum while as potential energy is maximum

Step-by-step explanation:

At the top most point of the flight since it cannot reach any further up in the vertical direction thus the potential energy at this position shall be maximum. Now since the total energy of the projectile is conserved so the remaining kinetic energy shall be minimum at that point so as the sum of the kinetic and potential energies remain constant.
