Question

A bus starting from rest moves with a uniform acceleration of 0.1m/s2 for 2 minutes. What is the distance travelled by the bus? a) 880m b) 660m c)720m d)770m

Answer 1

Explanation:

the distance travelled by bus is 720 m

Answer 2

Given :-

★ Acceleration, a = 0.1 m/s²

★ Time, t = 2 minutes = 120 sec

★ u =0 m/s

To Find :-

★ Distance, s =?

Solution :-

At first, we need to find v (Final velocity)

We know,

v = u +at

Substituting the values, we get

⟹ v = 0 + (0.1) × 120

⟹ v = 12 m/s

To find s (distance) , we need to use 3rd equation of motion.

We know,

$\sf v^2-u^2=2as$

Where,

V = Final velocity = 12 m/s

Substituting the given values, we get

⟹ (12)² -(0)² = 2 × (0.1) ×s

⟹ s = 720 m

Hence,

the distance traveled by bus is 720 m.

(c) is the correct option.
