Answer:

First find x and y at given parameters:

  • x = (v₀cosθ)t = (123 cos60°)t = 61.5t
  • y = h + (v₀sinθ)t - 16t² = 0 + (123 sin 60°)t - 16t² = 106.52t - 16t²

Maximum height is at vertex. Time is:

  • t = -106.52/-32 = 3.3 seconds

Maximum height is:

  • y = 106.52*3.3  - 16(3.3)² = 177.3 ft

Horizontal distance:

  • x = 61.5*3.3 = 203 feet

Time to hit the ground:

  • 106.52t - 16t² = 0
  • 16t = 106.52 (t = 0 is discounted)
  • t = 106.52/16
  • t = 6.7 seconds
