Answer:
<u>First find x and y at given parameters:</u>
- x = (v₀cosθ)t = (123 cos60°)t = 61.5t
- y = h + (v₀sinθ)t - 16t² = 0 + (123 sin 60°)t - 16t² = 106.52t - 16t²
<u>Maximum height is at vertex. Time is:</u>
- t = -106.52/-32 = 3.3 seconds
<u>Maximum height is:</u>
- y = 106.52*3.3 - 16(3.3)² = 177.3 ft
<u>Horizontal distance:</u>
<u>Time to hit the ground:</u>
- 106.52t - 16t² = 0
- 16t = 106.52 (t = 0 is discounted)
- t = 106.52/16
- t = 6.7 seconds
C and D apply to your expression.
Hello.
Max has 8 stickers. 8 x 6 = 48, and Alex has 6 times the amount.
F(-8)=8^2-3(-8)
=64+24
=88
Hope this can help.
