Answer 1

Given :-

A body starts from rest and acquires a velocity 20 meter per second in 5 second

To Find :-

Acceleration

Solution :-

We know that

a = (v - u)/t

a = (20 - 0)/5

a = 20/5

a = 4

Hence

Acceleration is 4 m/s²

• 1st equation of motion

v = u + at

• 2nd equation of motion

s = ut + 1/2 × at²

• 3rd equation of motion

v² - u² = 2as
