A motorcyclist starts from rest and reaches a speed of $6\ m/s$ after travelling with uniform acceleration for $3\ second$. What is his acceleration of the motorcycle?

As given, the motorcyclist starts from rest and reaches a speed of $6\ m/s$ after travelling with uniform acceleration for $3\ second$. 

Here, initial velocity $u=0$

Final velocity $v=6\ m/s$

Time $t=3\ sec.$

Let the acceleration in motorcycle be $a$.

On using the equation of motion, $v=u+at$

$6=0+3\times a$

Or $3a=6$

Or $a=\frac{6}{3}$

Or $a=2\ m/s^2$

Therefore, the acceleration in motorcycle is $2\ m/s^2$.
