Question

A base ball is thrown straight upward what is the acceleration of the ball at its highest point?

A) 0

B) 1/2 g downward

C) g downward

D) 1/2 g upward

Explain

Answer 1

Acceleration of the ball at the highest point is g downwards



The ball reaches its highest point when its velocity is zero; the acceleration of gravity is never zero (it is always 9.8 m/s² downward)

Gravitational force is acting on every object every time. At the highest point the velocity is zero but still the ball is under the influence of gravity ,here the acceleration due to gravity is acting downwards
