A 2.1 103-kg car starts from rest at the top of a 5.9-m-long driveway that is inclined at 19° with the horizontal. If an average friction force of 4.0 103 N impedes the motion, find the speed of the car at the bottom of the driveway.

  • physics - ,

    KE = mv²/2,
    W(fr)=F(fr) •s•sinα.
    m•g•s•sinα=mv²/2+F(fr) •s•sinα.
    Solve for ‘v’
