Question

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

Answer 1

Acceleration = final speed - initial speed / time

Acceleration = 6 m/s  - 0 / 3s

Acceleration = 6m/s / 3s

Acceleration = 2 m/s^2

Answer 2

Answer:

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

Step-by-step explanation:

$\displaystyle acceleration = \frac{final \ velocity - initial \ velocity}{elapsed \ time}$

$\displaystyle A = \frac{V_f - V_i}{t}$

The initial velocity is 0 m/s.

The final velocity is 6 m/s.

The elapsed time is 3 s.

$\displaystyle A = \frac{6 - 0}{3}$

$\displaystyle A = \frac{6}{3}=2$

The acceleration is 2 m/s².
