Work and Kinetic Energy

  1. Jul 24, 2009 #1
    An object of mass 10.0 kg is released from the top of an inclined plane which makes an angle of inclination of 30.0� with the horizontal. The object slides along the inclined plane. The questions refer to the instant when the object has traveled through a distance of 2.00 m measured along the slope. The coefficient of kinetic friction between the mass and the surface is 0.200. Use g = 10.0 m/s2. How much work is done by gravity?

    gravity is a conservative force which means that only the change in vertical height (not distance travelled) matters when measuring work done by gravity.
