use the following object model h=-16t^2+s where t is measured in seconds and h is measured in feet to find the time required for an object to reach the ground from height of s=200 feet

Question

HELP ME STEP BY STEP PLZZZZ!

Answer 1

h(t) = -16t² + 200

On the ground, h=0, so set h(t)=0 and solve for t.

-16t² + 200 = 0

16t² = 200

t² = 200/16

t = √(200/16) sec = ? sec
