A 89.0 N grocery cart is pushed 13.0 m along an aisle by a shopper who exerts a constant horizontal force of 40.0 N. If all frictional forces are neglected and the cart starts from rest, what is the grocery cart's final speed?

  • physics - ,

    net force=mass*acceleration
    40-friction= mass* a

    find a.
    then,

    vf^2=2a*distance

  • physics - ,

    8.94
