Question

A ball is dropped from a height of 36 feet. The quadratic equation

d=1/2 gt^2

is used to calculate the distance (d) the ball has fallen after t seconds. The constant g is the acceleration of gravity, 9.8m/s^2. How long does it take the ball to hit the ground?


A ball in problem 2 is dropped again, from a different height. This time, it takes 3 seconds to hit the ground. How far does it fall?
for 1.

d= 36 ft
g = 9.8
find t.
t=?
plug it in and find the answer

for 2.

t=3
g=9.8

find d

d=?
