A student wants to toss a textbook to his roomate who is leaning out of a window directly above him. He throws the book upwards with an initial velocity of 8.0 m/s. The roomate catches it while it is travelling at 3.0 m/s upward. A. How long was the book in the air? B. How far vertically did the book travel? C. Redo the problem, and have the roomate catch the book as it is travelling 3.0 m/s downward. What is the time and displacement now?

2. A student wants to toss a textbook to his roomate who is leaning out of a window directly above him. He throws the book upwards with an initial velocity of 8.0 m/s. The roomate catches it while it is travelling at 3.0 m/s upward. 

A. How long was the book in the air?

B. How far vertically did the book travel?

C. Redo the problem, and have the roomate catch the book as it is travelling 3.0 m/s downward. What is the time and displacement now?

 

3. A man is standing on the edge of a 20.0 m high cliff. He throws a rock vertically with an initial velocity of 10.0 m/s 

A. How high does the rock go? (Remember that at its max height v = 0 m/s)

B. How long does it take to reach it max height?
