Question

During the Superbowl, the quarterback throws the ball to a receiver 35 m downfield. The ball leaves the quarterback’s hand at a height of 2 m and at an angle of 35◦ above the ground. The receiver catches the ball, leaping into the air above the defender, catching the ball one-handed at a height of 3.5 m above the ground.

(i) Draw what you think is going on clearly indicating the information that you do know and the information you need to find.

(ii) Using the kinematic equations, derive an equation for the x-component of the initial velocity and compute its value.

(iii) Thus, what is the initial velocity vector (magnitude in mph and direction.)
