Question

What is the acceleration of a bike that goes from rest to 40m/h in 2 second?

Answer 1

• Initial velocity=u=0m/s
• Final velocity=40m/s=v
• Time=t=2s

`\\ \tt\longmapsto Acceleration=(v-u)/(t)`

`\\ \tt\longmapsto Acceleration=(40-0)/(2)`

`\\ \tt\longmapsto Acceleration=(40)/(2)`

`\\ \tt\longmapsto Acceleration=20m/s^2`
