Julie throws a ball to her friend Sarah. The ball leaves Julie’s hand a distance 1.0 m above the ground with an initial speed of 10 m/s at an angle 30◦ with respect to the horizontal. Sarah catches the ball 1.0 m above the ground.

(a) What is the horizontal component of the ball’s velocity right before Sarah catches it?

(b) What is the vertical component of the ball’s velocity right before Sarah catches it?

(c) What is the time the ball is in the air?

(d) What is the distance between the two girls?

(e) After catching the ball, Sarah throws it back to Julie. However, Sarah throws it too hard so it is over Julie’s head when it reaches Julie’s horizontal position. Assume the ball leaves Sarah’s hand a distance 1.0 m above the ground, reaches a maximum height of 6 m above the ground, and takes 1.115 sec to get directly over Julie’s head. What is the speed of the ball and the angle with the horizontal when it leaves Sarah’s hand?

(f) How high above the ground will the ball be when it gets to Julie?

As a quarterback throws the football, it leaves his hand at a height of h and at an initial speed of v0 at an angle θ above the horizontal. The receiver can’t get to the football in time and it falls onto the field. What is the ball’s speed as it hits the ground? Solve this problem in two ways: (a) using kinematics, explicitly calculating the trajectory the ball takes (b) using conservation of (kinetic + potential) energy
