# An object takes 5 s to reach the ground from a height of 5 m on a planet. What is the value of g on the planet? - Science and Technology 1

Short Note
Sum

An object takes 5 s to reach the ground from a height of 5 m on a planet. What is the value of g on the planet?

#### Solution

Here, u = 0
S = 5 m
t = 5 s
From second equation of motion, we have

$S = ut + \frac{1}{2}g t^2$
$5 = \frac{1}{2}g(5 )^2$
$g = \frac{10}{25} = 0 . 4 m/ s^2$

Hence, the value of g on the planet is 0.4 m/s2.

Concept: Variation in Value of g
