Question

A soccer player kicks a ball, and the height of the ball in feet as a function of time in seconds can be modeled by the function h(t) = –16t2 + 46.7t + 0.5. How many seconds will it take the ball to hit the ground after it has been kicked? Round your answer to the nearest tenth of a second. 0.1 seconds 0.5 seconds 1.5 seconds 2.9 seconds

Answer 2

The correct one is D) 2.9secomds

Explanation:

I have included a picture with a detailed explanation.

Wherever I've written x instead of t, just ignore it.

Oh, one more thing. We've set the function equal to zero because we're asked how many seconds does it take for the ball to HIT THE GROUND.

When an object hits the ground, isn't it's height equal to zero???
