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:
Time to hit the ground:
- 106.52t - 16t² = 0
- 16t = 106.52 (t = 0 is discounted)
- t = 106.52/16
- t = 6.7 seconds
