Term1/9

A hammer is dropped off a roof of an apartment building that is 80 meters high How long will it take to hit the ground

Definition1/9

The hammer will take square-root(2x80/9.8)= 4.04 seconds to hit the ground.

The distance is related to the time by s=v0t + 1/2 gt^2 where vo, the initial velocity is=0.

The answer is 4.04 or rounded is 4 seconds.
