Question

the height of a projectile launched upward at a speed of 32 feet/second from a height of 128 feet is given by the function h(t) = $-16tx^{2} + 32t+128.$ how long will it take the projectile to hit the ground ?

Answer 1

Answer:

It would take the projectile 4 seconds

T = 4

Step-by-step explanation:

g = 32 feets/ seconds (s)

s = 128 feet

t = ?

g = s

g = s t

32 = 128

t

Cross multiply

32t = 128

t = 128

32

t = 4 seconds
