Q1. A superball with a mass of 62.50 g is dropped from a height of 1.70 m. It rebounds to a height of 1.47 m.

What is the change in its linear momentum throughout the collision with the floor? The acceleration of gravity is 9.8 m/s2.

Q2. A new circus act is called the Texas Tumblers. Lovely Mary Belle swings from a trapeze, projects herself at an angle of 53, and is supposed to be caught by Joe Bob, whose hands are 6.10 above and 8.02 horizontally from her launch point. You can ignore air resistance. For the initial speed calculated in part A, what is the direction of her velocity while Mary Belle reaches Joe Bob?
