A matchbox car with mass M rolls down a ramp, starting from rest. It takes a time T to roll a distance L on the ramp. What is the car’s acceleration down the ramp?

  • Physics -

    assuming linear acceleration.

    avg velocity=L/T
    but avg velocity= 1/2 Vf

    Vf=2L/T

    but Vf=at
    2L/T=aT
    solve for a
