Problema Solution
. The ball's height
h
(in feet) after
t
seconds is given by the following.
=h+2−18t16t2
Find all values of
t
for which the ball's height is
6
Answer provided by our tutors
Assuming h = 2 + 18t - 16t^2 we need to solve the quadratic equation:
2 + 18t - 16t^2 = 6

........
t1 = 0.30 s
t2 = 0.82 s
The values for t for which the ball is 6 feet are: 0.30 s and 0.82 s.
