Mathematics: Leyla drops a penny from a height of 150 m. how long will it take the penny to hit the ground? use the formula h(t)=−4.9t^2+vt+h , where v is the initial velocity and h is the initial height. round to the nearest tenth of a second.

To determine the time it takes for the penny to reach the ground, we use the relation of height and time given above. We do as follows:

0 =−4.9t^2+(0)t+150
t = sqrt( 150/4.9)
t = 5.53 s

Hope this answers the question. Have a nice day.
