I'm working on the following problem:
a monkey is strapped to a sled and both are given an initial speed of 4.0 m/s upa 20 degrees inclined track. The combined mass of monkey and sled is 20 kg, and the coefficient of kinetic friction between the sled and the incline is 0.20. How far up the incline do the monkey and sled move?
Using the conservation of energy equation, I knowthat
KEi + PEi + Wnc = KEf +PEf
Since both PEi and KEf are 0, the equation is as follows:
KEi+Wnc=PEf
how do i find Wnc?
