A basketball player jumps straigh up to launch a long jump shot at an angle of 45 degrees with the horizontal and a speed of 15 m/s. The 78 kg player is momentarily at rest at the top of his jump just beforethe shot is released, with his feet 0.80 m above the floor. The mass of a basketball is 0.62 kg. Treat the player as a point particle. Assume the ball is launched to the right (positive x and y)
A.) What is the players velocity immediatley after the shot is realeased (break up into vertical and horizontal components/ answer ___i+___j)
B.) How far from his original position does he land?
