Question

The equation d= 4.9t^2 represents the distance (d) an object falls in time. In the equation, d is in meters, and t is in seconds. If an object falls a total distance of 1.2 meters, approximately how long did it fall?

Answer 1

Answer:

0.495s

Step-by-step explanation:

1.2=4.9t^2

t = √(1.2/4.9)

t=0.49487...=0.495s
