chuck drops a rock from a height of 70 m. how long will it take the rock to hit the ground?

use the formula h(t)=−4.9t^2+v0t+h0, where v0 is the initial velocity and h0 is the initial height.

round to the nearest tenth of a second. enter your numeric answer.

3.77 rounded is 3.8

Step-by-step explanation:

0=-4.9t^2+70

   +4.9t^2

    4.9t^2=70

   divided by 4.9 on (both 4.9 and 70)

 t^2=squareroot 14.285= 3.77
