Question

2) 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?
Give reason ​

Answer 1

Answer:

Explanation:

time taken to reach the ground=5s

height =5m

u=0

g=acceleration due to gravity

from second equation of motion

s=ut+1/2gt^2

5=0*5+1/2g*5*5

5=12.5*g

g=5/12.5

=0.4m/s^2
