Question
A ball is thrown upwards. Its acceleration is:
A downward during ascent and upward during descent
B upward during ascent and downward during descent
downward at all times except at the very top, when it is zero
D downward during both ascent and descent
A ball is thrown straight up, reaches a maximum height, then falls to its initial height. Make a statement about the direction of the
velocity and acceleration as the ball is coming down.
(A Its velocity points downward and its acceleration points upward.
(B Both its velocity and its acceleration point upward.
Its velocity points upward and its acceleration points downward.
Both its velocity and its acceleration point downward.
