During pre-season training of football team, the players are practicing punts by kicking balls in to an empty pool which is 3 meters deep. For one of the kicks, the ball lands in the bottom of the pool at a horizontal distance of 38.1 meters, after having spent 2.2 seconds in the air. [You can assume g '10 m/s2 ; Ignore the size of the ball; Ignore air resistance. Remember, velocity is a vector!] (a) Calculate the ball’s initial velocity. (b) Determine the highest point of the ball’s trajectory. (c) Calculate the ball’s final velocity, as it hits the bottom of the pool.

Skeet Shooting is an Olympic sport for rifle marksmen. A skeet is a clay target. A lady marksman goes out to practice and sets her skeet launcher at a position 25 meters north and 40 meters west from where she intends to stand. When she yells “Pull!”, a skeet is launched due East at an angle of 37 degrees above the ground with an initial speed, vo. The marksman only fires due north. Two seconds after she yells “Pull!”, the bullet from her gun hits the clay skeet in the air. At what height did the clay skeet shatter? Neglect air friction effects. {Use sin(37o) = 3/5; cos(37o) = 4/5; and g = 10 m/s2 }
