Pulling a Cart Up an Incline at Constant Speed. Consider a cart being pulled up an inclined plane at constant speed by a student during a Physics lab. The applied force on the cart (say 18 N) is directed parallel to the incline to cause the cart to be displaced parallel to the incline for a given displacement (say 0.7 m). The initial energy plus the work done by the external force equals the final energy. If the cart begins with 0 Joules of energy (this is just another made up value), and the student does 12.6 Joules of work (F•d•cosine of angle = 18 N•0.7 m•cosine 0 degrees = 12.6 J), then the cart will finish with 12.6 Joules of mechanical energy.
The final energy (12.6 J) is ?

2. Pulling a Cart Up an Incline at Constant Speed. Consider a cart being pulled up an inclined plane at constant speed by a student during a Physics lab. The applied force on the cart (say 18 N) is directed parallel to the incline to cause the cart to be displaced parallel to the incline for a given displacement (say 0.7 m). The initial energy plus the work done by the external force equals the final energy. If the cart begins with o Joules of energy (this is just another made up value), and the student does 12.6 Joules of work (F-d-cosine of angle = 18 N-0.7 m.cosine o degrees = 12.6 J), then the cart will finish with 12.6 Joules of mechanical energy. The final energy (12.6 J) is? Final Energy = WPU-QSF-ACAD-82A Rev. 00 (09.15.20) d=0.70 m Initial Energy = 0J- F=18 N 13
