Question

The acceleration of gravity is 9.8m/s2. How fast will an object be moving if it falls for three seconds?

A.294m/s

B.9.8m/s

C.29.4mi/hr

D.29.4m/s

Answer 1

Acceleration

`(distace)/(time)`

When we cross multiply, distance will be equal to acceleration multiply by time

Distance = acceleration x time

Distance = 9.8 x 3

= 29.4 m/s
