1.	a. An object takes 5 s to reach the grondfrom a height of 5 m on a planet.What is the value of g on the planet?Ans: 0.4 m/s2
Answer» We will use the equation of motions: THE EQUATION TO USE :S =ut + 1/2gt^2 Where S is the displacement, t the time u the initial velocity, g the acceleration due to gravity: In this question:u = 0S = 5mt = 5 Substituting in the formula we have :5 = 1/2 × 25 × g5 = 12.5gg = 0.4 m/s²

Answer»

We will use the equation of motions:

THE EQUATION TO USE :S =ut + 1/2gt^2

Where S is the displacement, t the time u the initial velocity, g the acceleration due to gravity:

In this question:u = 0S = 5mt = 5

Substituting in the formula we have :5 = 1/2 × 25 × g5 = 12.5gg = 0.4 m/s²
