A toy car accelerates at a constant rate from rest to a speed of 4 m/s in a time of 0.55 s. What was the magnitude of the acceleration, in units of m/s2?

Answer :

  • initial velocity=u=0m/s
  • Final velocity=v=4m/s
  • Time=t=0.5s

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

[tex]\\ \sf\longmapsto Acceleration=\dfrac{4-0}{0.5}[/tex]

[tex]\\ \sf\longmapsto Acceleration=\dfrac{4}{0.5}[/tex]

[tex]\\ \sf\longmapsto Acceleration=8m/s^2[/tex]
