Question

A motorcyclist starts from rest and reaches a speed of 6m/s after travelling with uniform acceleration for 3s .

the question is what is his acceleration?
by calculation​

Answer 1

`\Huge \boxed{\mathrm{2 \ m/s^2 }}`

Explanation:

`\displaystyle acceleration = (final \ velocity - initial \ velocity)/(elapsed \ time)`

`\displaystyle A = (V_f - V_i)/(t)`

The initial velocity is 0 m/s.

The final velocity is 6 m/s.

The elapsed time is 3 s.

`\displaystyle A = (6 - 0)/(3)`

`\displaystyle A = (6)/(3)=2`

The acceleration is 2 m/s².

Answer 2

Acceleration = final speed - initial speed / time

Acceleration = 6 m/s - 0 / 3s

Acceleration = 6m/s / 3s

Acceleration = 2 m/s^2
