1) From a standstill (vQB = (J), a quarterback throws a football at angler? with speed vb. A receiver, running in line with the throw at speed or, catches the football as it lands. In this exercise, we explore what the hall's trajectory looks like in the frame of the receiver. (i) What are the r and 3,.- components of the football's velocity in the frame of the receiver as the hall lands? (ii) At what angle 6r does the ball land in the receiver's frame? Is 6r steeper or shallower than 9? (iii) At what speed must the receiver run for the ball to fall directly downwards in their frame? (iv) If or = \"a cos(6)/2, then how far does the ball travel in the receiver's frame? Express your answer in terms of :9, Us: and g
