Question

1. What is the acceleration of a rock thrown straight upward on the way up? At the top of its flight? On the way down? Assume there is no air resistance.

Answer 1

Explanation:

as gravitational force is the only major force acting over the rock therefore .

the main acceleration would be g m/s^2 in magnitude .

yet while going up this value would be negative at the top and at the bottom or while going down this value would be positive in nature .....

hope it helps
