Use the formula 4.9t^2 +vot=s, where t is the time in seconds, vo is the initial velocity, and s is the distance in meters.

Approximately how far will an object fall in 4 seonds, if it is thrown downward at an initial velocity of 20 meters per second (vo) from a helicopter?

Is this right?

4.9(t)^2+vot=s

4.9(4)^2+20(4)=s

(4.9)(16)+80=s

78.4 +80=s

158.4 meters
