Question

The path of a baseball being hit by a bat is modeled by the function b(t) = -16t^2 + 50t + 3. Where the height of the ball is in feet and the time is in seconds.

a. When will the baseball hit the ground?


b. Find the height of the ball after 2 seconds.

Answer 1

a) 3 sec

b) 39 feet

Explanation:

a) b(0) = -16(b)² + 50(0) + 3

b(0) = 3

b) b(2) = -16(2)² + 50(2) + 3

b(2) = -64 + 100 + 3

b(2) = 36 + 3
