1. The problem statement, all variables and given/known data A toy car of mass 20kg is pushed up the entirety of a 35m slope, inclined at an angle of arcsin(2/7) to the horizontal. The height at the top of the slope is 10m. The applied force which pushes the car up the slope is 100N, initially, the toy car is stationary. Calculate the work done, power and efficiency of the system: 3. The attempt at a solution For the work done, am I correct in thinking it would be the work done by the applied force, i.e.: WD=100x35=3500J? I'd like to do this 'step by step' so to speak, any help would be much appreciated, thanks!
