From what height was the rock thrown

Reference no: EM13707606

Problem: A rock thrown with speed 10.5 m/s and launch angle 30.0 degree (above the horizontal) travels a horizontal distance of d = 15.0m before hitting the ground.

Part A: From what height was the rock thrown? Use the value g = 9.810 m/s² for the free-fall acceleration.

I need help to determine from what height was the rock thrown.
