Question

PLEASE HELP I HAVE NO CLUE WHAT IM DOING. Parents finna ground me if I don't do this tonight.

Answer 1

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
