Question

A motor cyclist starts from rest and reaches a speed of 6m/s after travelling with uniform acceleration for 3s. What is his acceleration
​

Answer 1

Answer:

2m/s²

Explanation:

When an object starts or at its state of rest it has an Initial speed U = 0

Final speed = 6m/s

total time taken for the acceleration = 3s

Acceleration =?

Acceleration is the change in velocity (speed) with time

OR

Time rate of change of velocity

Acceleration = Change in Speed(velocity)

Time taken

Hence,

Acceleration = V - U

t

a = 6 - 0

3

a = 6

3

a = 2m/s²
