Use the formula to determine how long it takes the ball to return to the earth.
:
The formula: h = -16t^2 + 150t + 5
h = 0 when it hits the ground, so we have
-16t^2 + 150t + 5 = 0
Solve this using the quadratic formula; a=-16; b=150; c=5
:
You should get a positive solution: t = 9.4 seconds
:
looks like this
