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 m/s². How much work is done by gravity? A) 100 J B) 20.0 J C) 0 J D) 10.0 J E) 131 J

Question

Quizplus · Accepted Answer

The work done by gravity is calculated using the formula: Work = m * g * d * sin(θ). Substituting the given values: Work = 10 kg * 10 m/s² * 2 m * sin(30°) = 100 J.
