Answer:
The instantaneous velocity at the top of its flight is v = 0 m/s
Explanation:
From the question we are told that
The initial velocity is u = 25.0 m/s
Generally an instantaneous velocity can be defined as the velocity of an object at an instant of time period during its motion, , generally the velocity of a object at it maximum height is 0 m/s hence the instantaneous velocity of the paintball at the top of its flight is 0 m/s
