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

$\\ \tt\longmapsto Acceleration=\dfrac{v-u}{t}$

$\\ \tt\longmapsto Acceleration=\dfrac{40-0}{2}$

$\\ \tt\longmapsto Acceleration=\dfrac{40}{2}$

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