a truck with a mass of 1,500 kg is parked on a hill with a slope of 7 degrees. the parking break is released and the truck starts to roll down the hill.
a) assuming friction is negligible what will by the force that moves the car down the hill?

b) what will the speed of the carbs after50 seconds?

  1. friction was neglibible but it was parked on the hill. Go figure.

    weight down the hill: mgsin7
    that is the force down the hill.

    a= F/m

    vf=at=F/m * time
