H = 5 + ut - 16t^2
When the balls falls back to the ground, h = 0
0 = 5 + 3.2u - 16(3.2)^2
0 = 5 + 3.2u - 163.84
0 = 3.2u - 158.84
3.2u = 158.84
u = 158.84/3.2 = 49.6 ft/s
Required equation is
h = 5 + 49.6t - 16t^2
Answer:
Alright well Graph each side of the equation. The solution is the x - value of the point of intersection k = 4.582 Hope this helps :)
Step-by-step explanation:
A) 51, assuming this is a *right* triangle:
38^2+34^2 = 50.99^2, rounding 51!!
