Question

A bus starting from rest moves
with a uniform acceleration of
0.1 m sº for 2 minutes. Find (a)
the speed acquired. (b) the
distance travelled.
​

Answer 1

As when a body starts from rest then its Initial Velocity becomes Zero.

Given,

Acceleration (a) = 0.1 m/s^2

time (t) = 2 min = 2 x 60 s = 120 s

Initial Velocity (u) = 0 m/s

In order to find Velocity we will apply First Equation of Motion :-

=> V = u + at

=> V = 0 + 0.1 x 120

=> V = 0 + 12 m/s

=> V = 12 m/s

Again In order to find Distance transversed we will apply third equation of Motion.

=> V^2 = u^2 + 2aS

=> (12)^2 = 0^2 + 2 x 0.1 x S

=> 144 = 0 + 0.2 x S

=> S = 144/0.2 m

=> S = 720 m

Answer 2

Explanation:

distance is 720 m and velocity is 12m/s
