Question 175007: Suppose Charlie O達rian of the Braves hits a baseball straight upward at 150 ft/sec from a height of 5 ft.
Use the formula to determine how long it takes the ball to return to the earth.
You can put this solution on YOUR website! Charlie O達rian of the Braves hits a baseball straight upward at 150 ft/sec from a height of 5 ft.
Use the form-ula to determine how long it takes the ball to return to the earth.
-----------
h(t) = -16t^2 + vo(t) + so
Your problem:
h(t) = -16t^2 + 150t + 5
---------------------------
Height is zero when the ball hits the ground.
0 = -16t^2 + 150t + 5
t = [-150 +- sqrt(150^2 -4*-16*5)]/[-32]
Positive solution:
t = 9.41 seconds
