5. A football is kicked off with an initial speed of 64 ft/s at a projection angle of 45 °. A receiver 180 ft. away in the direction of the kick starts running to meet the ball at that instant. What must be his average speed if he is to catch the ball just before it hits the ground? Neglect air resistance. Answer: 5.61 m/s um elevation 1

One of the fastest recorded pitches in major league baseball, thrown by Tim Lincecum in 2009, was clocked at 101.0 mi/h (Fig. P3.8). If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically by the time it reached home plate, 60.5 ft away? Figure P3.8 Tim Lincecum throws a baseball.

In Canadian football, after a touchdown the team has the opportunity to earn one more point by kicking the ball over the bar between the goal posts. The bar is 10.0 ftft above the ground, and the ball is kicked from ground level, 36.0 ftft horizontally from the bar in (Figure 1). Football regulations are stated in English units, but convert to SI units for this problem. If the ball is kicked at 39.0 ∘∘ above the horizontal, what must its initial speed be if it is just to clear the bar? Express your answer in m/sm/s
