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 … WebNov 12, 2024 · The net work done by friction on the body of the snake is 333.35J. Explanation: Work done is given by . W = F × s. Where W is the Work done. F is the force . and s is the distance covered . Since we are to determine the work done by friction, then we will determine the frictional force. The frictional force is given by . f = μN = μw
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. WebWork is done whenever energy is transferred from one store to another. Mechanical work involves using a force to move an object. Electrical work involves a current transferring energy. Work done (J) = Force (N) x Distance (m) Example: During braking, a force of 2000N is applied to the brakes of a car. The car takes 20m to come to a stop.
