Question:

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 11.2 m/s and a launch angle of 31.5° 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 balls 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?
