You throw a ball vertically upward, and as it leaves your hand, its speed is 10.0 m/s.

a. How high (in m) does it rise above the level where it leaves your hand?

b. How long (in s) does it take to reach its highest point?

c. How long (in s) does the ball take to return to the level where it left your hand after it reaches its highest point?

d. Assume that the upward direction is positive and the downward direction is negative. What is the ball’s velocity (in m/s) when it returns to the level where it left your hand? (Indicate the direction with the sign of your answer.)
