A 2 kg ball is dropped from a height of 1/5 m. It bounces off the floor with a velocity of 1 m/s. What is the impulse (magnitude and direction) applied to the ball during the collision with the floor?
While fixing the spacecraft in outer space, Trillian needs her physics book. Ollie tosses her the book with a velocity of 10 m/s. The book's mass is 3 kg, and Trillian's mass is 57 kg. Once she catches the book, what is her velocity?
