Question

A motorcycle starts from rest . If its gain an acceleration of 2m/s^2 in 5 second , Calculate the final velocity.

✌✌✌✌​

Answer 1

• initial velocity=u=0m/s
• Acceleration=a=2m/s^2
• Time=t=5s
• Final velocity=v=?

Using first equation of kinematics

`\\ \sf\longmapsto v=u+at`

`\\ \sf\longmapsto v=0+2(5)`

`\\ \sf\longmapsto v=10m/s`
