Use the formula h(t) = -16t^2 + vt + s,
where t = time in air,
v = starting upward velocity,
s = the objects starting height.
from ground (s), the starting height is 0,
the ball's initial velocity (v) 25 feet per second
Solve:
v - 16t^2 + (25)t + 0
= -16t^2 + 25t. 0
Factor:
= -16t^2 + 25t
Find GCF:
0 = -16t^2 + 25t
Divide both sides by (t)
t(-16 + 25) = 0
t = 0; -16 + 25 = 0
Now Subtract 25 from both sides of equation:
-16 = -25
divide both sides by -16 to get -25/-16
= 1.56
Rounds to 1.60, or 1.6

X is equal to -1.
Step-by-step explanation:

You just have to arrange the equation such that the p is the only term at the left hand side of the equation. Express it in terms of r and m.
r = 1/2*m²*p
Divide both left and right hand side equations by 1/2*m²
p = r/(1/2 *m²)
Take the reciprocal of 1/2 and multiply it. The final answer is:
p = 2r/m²
