Question

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

Answer 1

here v is final velocity
and u is initial velocity
t is time

hope this helps u
cheers

Answer 2

u=0
v=6m/s
t=3 sec
1st eq of motion
v=u+at
a=(v-u)/t
= (6-0)/3
= 2 m/s²
