Question

A Bus Starts from rest. if the acceleration is 2 m/s^2, find:-

i) The distance travelled.
ii) the velocity after 2 seconds.

please answer this.

Answer 1

Answer:

Given :-

A bus starts from rest.

Acceleration = 2 m/s²

To Find :-

i) The distance travelled.

ii) the velocity after 2 seconds

Solution :-

Finding velocity after 2 second

v = u + at

v = 0 + (2)(2)

v = 0 + 4

v = 4 m/s

Now

We know that

s = ut + ½ × at²

s = 0(2) + ½ × (2)(2)²

s = 0 + ½ × (2)(4)

s = ½ × 8

s = 4

Hence,

Distance travelled = 4 m

Velocity after 2 second = 4 m/s
