An object is thrown vertically upward.
a) What are its velocity and acceleration when it reaches its highest altitude?
b) What is its acceleration on its way downward half a meter above the ground?


My ans:
a) velocity is zero and acceleration is 9.8 m/s^2
b) i am not sure but i think acceleration should still be 9.8m/s^2
