1. A player lines up to kick a 40 m goal. In the first attempt, the ball has an initial velocity of 20 m/s at angle of 55.0 degrees. The goal posts are 3 m high. Once the ball passes above the field goal post (i.e., after it has travelled 40 m in the horizontal direction), it is deemed successful. (a) Determine if the goal kicker's first attempt is successful. (b) If the kicker changes the angle of kicking to 30 degrees and the initial velocity so that it JUST reaches the goal post. Determine the new initial velocity of ball.

At serve, a tennis player aims to hit the ball horizontally (Figure 1). What minimum speed is required for the ball to clear the 0.90-mm-high net about 15.0 mm from the server if the ball is "launched" from a height of hhh = 2.30 mm ?

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.
