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