From the top of a 90 m cliff aaron throws a ball directly, Ask an Expert

Academics

From the top of a 90 m cliff, Aaron throws a ball directly downwards with an initial velocity of 1.80 m/s.

1) What is the average velocity of the ball through this trip?

2) How long in seconds does the ball take to reach the ground?

3) What is in meters/second the velocity of the ball the minute it reaches the ground below?

4) At what position, in meters relative to the initial position did the instantaneous velocity of the ball equal the average velocity computed in the previous part?

5) How long in seconds will take it take the ball to have an instantaneous velocity equal the average velocity computed in the part c? Don't include units in the answer, use 10.0 m/s2 for g and use the upward direction as positive.
