Question

A bus starts from rest and attains 40km /h velocity after 20 seconds. Calculate the acceleration in km/h and m/s

Answer 1

Answer:

given

• u=0
• v=40km/h=40*5/18=11.11m/s
• t=20s
• a=v-u/t
• a=11.11-0/20=11.00/20=0.55m/s^2

Answer 2

acceleration will be 0.22 know/h^2

I hope it may help you to get the answer
