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

उत्तर
We have to find the value of uniform acceleration.
Initial velocity (u) = 0 m/s
Final velocity (v) = 6 m/s
Time taken (t) = 3s
Acceleration:
`a = (v-u)/t`
Put the values in the above equation to obtain the value of acceleration .
`a = (6-0)/3`
= `2 "m/s"^2`
