Question

# A bus starts from rest and keeps increasing its speed by 3 m/s every second. It covers a distance of ____ in 20 s.

Hint:

### 600 m

## The correct answer is: 600

### Given that,

The initial velocity, u = 0

The acceleration, a = 3 m/s^{2}

Time taken, t = 20 s

On using the second equation of motion we get,

s = ut + ½at^{2}

Or, s = 0 + ½ (3) (20)^{2}

Or, s = 600 m

Therefore, the distance covered by the bus is 600 m.

### An object starts from rest. It means that _____.

Rest implies that the body was stationary with respect to the ground. Any body which doesn't move has zero velocity, since it doesn't covers any distance. Thus, any body starting from rest has initial velocity= zero.
