Two people use a ramp to move a heavy box onto a truck. The box weighs 748 N and you exert a force of 187 N to move the box. What is the mechanical advantage of using the ramp?
(question 1) B, (mechanical to gravitational)
(question 2) D, (H)
(question 3) - 1 is gravitational potential energy, 2 is sound energy, 3 is electromagnetic energy and 4 is mechanical energy
(question four) C, (kinetic)
(question five) D, (4)
(question six) C, (The gravitational potential energy at point A is four times as large as that at point B.)
(question 7) A, 360 J
you only have a couple of numbers. What are you going to do with them?
what is mechanical advantage? The ratio of force produced to force exerted, right?
