Problema Solution
Tonisha hit a baseball into the air with an initial upward velocity of 48 feet per second. the height h in feet of the ball above the ground can be modeled by h= -16t^2 + 48t + 2, where t is the time in seconds after Tonisha hit the baseball. Find the time it takes the ball to reach 38 feet above the ground.
Answer provided by our tutors
We need to find t, t>0 such that h = 38 ft that is:
-16t^2 + 48t + 2 = 38

........
t = 1.5 s
After 1.5 seconds the ball will be 38 feet above the ground.
