For a science fair competition, a group of high school students build a kicker-machine that can launch a golf ball from the origin with a velocity of 39.5 m/s and initial angle of 30.4° with respect to the horizontal.
(a) Where will the golf ball fall back to the ground?
(b) How high will it be at the highest point of its trajectory?
(c) What is the ball's velocity vector (in Cartesian components) at the highest point of its trajectory?
(d) What is the ball's acceleration vector (in Cartesian components) at the highest point of its trajectory?
