Answer:
I answered this question previously on another post that was like this one. If this is correct you can text me at this number (301-232-7391) and i'll give you the cashapp so you can send me the 5 dollars :)
Step-by-step explanation:
8.5 feet(12 inches per foot)= 102 inches total
There are 102 inches in 8.5 feet
2x * 3x = 6x^2
2x * (-4) = 8x
7 * 3x = 21x
7 * (-4) = -28
6x^2 + 29x - 28
Let the only force acting on the ball is the gravity (free-failing) and the ball was initially stationary
vo = 0
s = vot + 1/2 gt^2
s = 1/2 x 10 x (2.2) ^2 = 24.2 m
the last one because 7*3=21 14*3=42 and 21*3=63
