Question

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

Answer 1

Answer:

9.8 OR 10 IS THE VALUE OF g

Answer 2

Answer:

Since we have the height and time we will use the following kinematics equation.

S = ut + 1/2gt²

Where :

S = height

u = initial velocity.

t = time in seconds

g = gravitational acceleration

In our case the initial velocity = 0

Doing the substitution we have :

5 = 0 × 5 + 1/2 × g × 5²

5 = 12.5g

g = 5/12.5

g = 0.4

The g on the planet is therefore 0.4m/s²
