A football quarterback throws a pass at an angle of 36°. He releases the pass 3.50 m behind the lineof scrimmage. His receiver left the line of scrimmage 2 s earlier, going straight down-field at a constantspeed of 7.50 m/s. With what speed must the quarterback throw theball so that the pass lands gently in the receiver's hands withoutthe receiver breaking stride? Assume that the ball is released at the same height it is caught and that the receiver is straightdown field from the quarterback at the time of release. (Ignore anyeffects due to air resistance.)
