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

Respuesta :

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

[tex]\\ \tt\longmapsto Acceleration=\dfrac{v-u}{t}[/tex]

[tex]\\ \tt\longmapsto Acceleration=\dfrac{40-0}{2}[/tex]

[tex]\\ \tt\longmapsto Acceleration=\dfrac{40}{2}[/tex]

[tex]\\ \tt\longmapsto Acceleration=20m/s^2[/tex]
