Sled physics problem
WebThe W nc term results from friction acting upon the sledder. The force of friction is given by the equation F frict = mu • F norm. For inclined planes the normal force is equal to the perpendicular component of the weight vector (see diagram at the right).

WebTherefore, the net force acting on the sled is zero, and the equation for the net force in the X-direction would be: Fnet,x = ΣFx = 0 3) a) For this case, since the sled is moving with a constant velocity to the left, it means that the net force in the X-direction is zero. WebSince 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.
