Question

A raindrop, mysteriously, falling on the Moon, hits thesurface

Answer 1

Answer:

The time that the drop is falling =35.875 s

Explanation:

Using one of newton's equation of motion

g = V-u/t ................ Equation 1

Where V = final velocity, u = initial velocity, g = acceleration due to gravity of the moon, t = time.

Note: for a dropping object, u = 0 m/s

g = V/t.................... Equation 2

making t the subject of equation 2 above

t = V/g................. Equation 3

Given: V= 57.4 m/s, g = 1.6 m/s²

Substituting these values into equation 3

t = 57.4/1.6

t = 35.875 s

t = 35.875 s

The time that the drop is falling = 35.875 s
