Question

A bus starting from rest moves with uniform motion acceleration of 0.1m/sec for 2 min. Its speed will be 1= 0.2m/sec
2= 0.12m/sec
3= 12.0m/sec
4= 1.20m/sec

Answer 1

Explanation:

let the speed be velocity

initial velocity = u = 0m/s

final velocity = v

time = 2min = 120s

acceleration = 0.1m/s^2

a = ( v - u )

t

0.1 = ( v - 0 )

120

( v - 0 ) = 0.1 ( transposing )

120

v - 0 = 0.1×120

v = 12

therefore the final velocity ( speed ) will be 12m/s

your answer is option 3
