Find the work done by friction
WebIn part A we're asked to find the work done by the friction force and so that is the friction force multiplied by the the component displacement parallel to the friction although we don't have to worry about that parallel … WebThe work done by friction is the force of friction times the distance traveled times the cosine of the angle between the friction force and displacement; hence, this gives us a way of finding the distance traveled after the person stops pushing. Solution

The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force on the sled by pulling on the rope.
WebFeb 20, 2011 · then you take the work due to friction so 60N*500m and get 30000J. Since friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 … To find the work done by friction, we'll plug in the size of the force of friction, which … however i used both methods: the kinematic way and the energy way. For the … WebNow the block is not made of ice but something solid that would make the surface friction significant. The coefficient of kinetic friction of the inclined plane with the block is 0.3. a) Calculate the work done by each force acting on the block. b) Also calculate the change in the kinetic energy of the block.
Web(a) Calculate the work done on a 1500-kg elevator car by its cable to lift it 40.0 m at constant speed, assuming friction averages 100 N. (b) What is the work done on the elevator car by the gravitational force in this process? (c) What is the total work done on the elevator car? 4. WebThe force of friction is given by f ( x) = μ ρ ( L − x) g The net force on the chain is ∑ F = F − μ ρ ( L − x) g Work done on the chain is the integral of force over distance, so W = ∫ 0 L F − μ ρ ( L − x) g d x Integrate and get …
