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?
