Leyla drops a penny from a height of 150 m.

gizmo_the_mogwai [7]

When the penny hits the ground, h will = 0.

So: Set h(t) = 0 = -4.9t^2 + 0t + 150 m

Then 4.9t^2 = 150, and so t^2 = sqrt(150 / 4.9) = plus or minus 5.53 sec.

We can use only the positive root, as we're measuring time.

t = 5.5 sec (answer)
