Physics

A 2600 kg truck traveling at 72 km/h slams on the brakes and skids to a stop. The frictional
force between the truck and the road is 8200 N. Calculate the mechanical work required to stop
the truck and the distance the truck travels before stops.

  1. work must equal 1/2 m v^2 change v to m/s.

    then 8200*distance= work above, calculate distance to stop
