Asked by Tim

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 12.9 m/s and initial angle of 31.7° with respect to the horizontal.

a) Where will the golf ball fall back to the ground?

Tries 0/99

b) How high will it be at the highest point of its trajectory?

Tries 0/99

c) What is the ball's velocity vector (in Cartesian components) at the highest point of its trajectory? First enter x, then y.

Tries 0/99

d) What is the ball's acceleration vector (in Cartesian components) at the highest point of its trajectory? First enter x, then y.

Tries 0/99
