- Communication 1. Determine whether or not the path travelled has an effect on the work being performed if the starting point and ending point remain the same. Consider cases when there is only one constant force acting on an object and other times when the forces acting on the object depend on the path. Give an example of each.A 600 N crate slides 12 m at constant speed down a ramp that is tilted 35° above horizontal. ▼ Part A How much work does gravity do on the crate as it slides the 12 m?

- Physics help! what is the work Wn done on the box by the normal force? so find Wn=____J * hint given background information "the work Ww done in the box of weight of the box is Ww= 1.8 J" next find the work of Wfk done on the box by the force of kinetic friction? give your answer in: Wfk=___J i have attached supporting details at the bottom.Several physical situations are described below. For each situation, simplify the work-energy equation by canceling any zero terms and any energy terms (whether KE or PE) which are unchanging. Explain each term which gets canceled. A Hot Wheels car starts from rest on top of an inclined plane and rolls down the incline through a loop and along a horizontal surface. Friction and air resistance have a significant effect on the car.
