A particle is accelerated uniformly from rest, so that after 10 seconds it has achieved a speed of 15 m/s. Find its acceleration.

1.5 m/s²

Explanation:

Applying,

a = (v-u)/t Equation 1

Where a = acceleration of the particle, v =  final velocity of the particle, u = Initial velocity of the particle, t = time.

From the question,

Given: u = 0 m/s (From rest), v = 15 m/s, t = 10 seconds

Substitute these values into equation 1

a = (15-0)/10

a = 15/10

a = 1.5 m/s²

its c its is a mixture of gases
