1. The problem statement, all variables and given/known data 2. Relevant equations W=Fx*d P=W/Δt 3. The attempt at a solution Shot in the dark but, 20 people with 60 kg mass=1200kg total mass. Weight=1200kg*9.8m/s^2=11760N. Force component along the incline is 11760N*sin(30)=5880N. Work=5880N* 10m=58800J.(The 10m was found from trig function of the angle 30). Power=58800J/60sec=980W. Answer is 980 watts?
