    Physics problem need help

    in Homework Help

    Posted

    Hey all, here is a problem that I have for homework and I can't figure it out. Any help will be appreciated.

     

    a 1650kg car accelerates from 15.9m/s to 28.1m/s in 8.31s.

    a.) what is the work done on the car?

    b.)what is the average power umed during acceleration?

    c.)what is the average force accelerating the car?

     

    So I know I have to use...

     

    Work = change in kinetic energy = 1/2 (m)v^2.

     

    Then what?

     

    Thanks ahead of time!
