Initial Velocity, u=0 m/s

Final Velocity, v=(?)

Acceleration, a=0.2 m/s²

Time, t=3 min = 180 s

Now, we know that

Uniform Acceleration, a= (v-u) / t

∴at = v-u

∴v = at + u

∴v = 0.2 * 180 + 0

∴v = 36 m/s or 10 km/h

Thus, velocity of the bus at the end of 3 minutes is 36 m/s.

v = u + at

given,

u = 0

a = 0.2 m⁻¹s

t = 3 min = 180 sec

therefore,

v = 0+ 0.2×180

v = 36 m⁻¹s
