Question

For a science fair competition, a group of High School students built a kicker-machine that can launch a golf ball from the origin with a velocity of 12.7 m/s and initial angle of 30.7degree with respect to the horizontal. Where will the golf ball fall back to the ground? How high will it be at the highest point of its trajectory? What is the ball's velocity vector (in Cartesian components) at the highest point of its trajectory? First enter x, then y. What is the ball's acceleration vector (in Cartesian components) at the highest point of its trajectory? First enter x, then y.

Explanation / Answer

a) horizontal distance = 14.44 m b)highest = 2.144m c) 10.92 m/s d) -9.8 j
