WebFriction. Friction is a force that opposes relative motion between surfaces in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface …
WebA number of problems can be caused by friction between two objects or materials. Since friction is a resistive force that slows down or prevents motion, it can be a nuisance, … clyde water billWebAnswer for Problem # 2 The wheels can't support torque about their center of rotation, so there is no force parallel to the incline at the contact point between wheel and incline. So there is only a normal force at the contact point between wheel and incline, as shown in the free body diagram below. cactus shower curtain kohlsWebSince 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 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s. cactus shower curtain interdesignsWebExpert Answer.
