WebIf the motor exerts a constant force of 300 N on the cable, determine the speed of the 20-kg crate when it travels s = 10 m up the plane, starting from rest. The coefficient of … WebOnce there is motion, friction is less and the coefficient of kinetic friction might be 0.30, so that a force of only 290 N f k = μ k N = ( 0.30) ( 980 N) = 290 N would keep it moving at a constant speed. If the floor were lubricated, both coefficients would be much smaller than they would be without lubrication.

WebIf the motor exerts a constant force of 300 N on the cable, determine the speed of the 28 kg crate when it travels s = 10m s = 10 m up the plane, starting from rest. The coefficient … WebAccording to Newton’s third law, the floor exerts a forward force F floor of 150 N on the system. Because all motion is horizontal, we can assume that no net force acts in the vertical direction, and the problem becomes one dimensional. As noted in the figure, the friction f opposes the motion and therefore acts opposite the direction of F floor. fine arts vs useful arts

WebVideo transcript. I'm going to show you some examples of how to solve problems involving work. Imagine a 4 kilogram trashcan. The trashcan is disgusting. So someone ties a string to it and pulls on the string with a force of 50 newtons. The force of kinetic friction on the trashcan while it slides is 30 newtons. WebIf the motor exerts a constant force of 300 N on the cable, determine the speed (ft/s) of the 20-kg crate when it travels s = 10 m up the plane, starting from rest. The coefficient … WebIf the crate moves at constant speed, findthe work done by the 150-N force andthe coefficient of kinetic friction between the crate and surface. A tension force of 175 N inclined at 20 degrees above the horizontal is used to pull a 40.0-kg packing crate a distance of 6.00 m on a rough surface. fine art technician jobs london
