1. The problem statement, all variables and given/known data A cart travels up a hill at a constant velocity in 2.5 (s). What power is developed by the cart? m=120 kg meters=12m θ=21° 2. Relevant equations P=w/t w=F(parallel)×meters×cosθ 3. The attempt at a solution P= w/t= Fdcosθ/2.5= F(12)(.93)/2.5= 11,2F/2.5= 4.5F How do I find F?
