Question

A bus accelerates from rest at the rate of 0.2 m/s2. What will be the velocity attained by it in 1 minute?

Answer 1

Answer:

72m/s

Explanation:

Initial velocity=0

Final velocity=?

Acceleration=0.2m/s square

Time=1 minute=60 seconds

Acceleration=Final velocity - Initial velocity/Time

0.2 = V-u/t

0.2. = V-0/60

0.2*60= V-0

12 =V-0

12+0=V

V or Final velocity =12m/s

Answer 2

initial speed=0 because bus accelerates from rest .

acceleration=o.2m/s2

time =1min=60sec

velocity v =u+at

Answer:

v=0+0.2multiply60=12.0m/s
