A braking force is applied to a 300-kg motorcycle to reduce its speed from 20.0m/s to 16.0m/s in 10.0s. Find the braking force.

  • physics - ,

    Deceleration:
    16 = 20 + Ta
    16 - 20 = 10a
    a = -0.4 m/s2
    Braking force = 300 X 0.4 = -120 N
    Please check the above calc and give comments!
