Question

Suppose an astronaut drops a feather from 1.4 m above the surface of the Moon. If the acceleration due to gravity on the Moon is 1.62 m/s2 downward, how long does it take the feather to hit the Moon's surface?

Answer 1

Solve the equation
(1/2)(1.62) t^2 = 1.4
That will give you the time, t

Answer 2

1.34
