An object that follows Hooke’s Law is hanging 2 m above the ground with a mass of 1.5 kg and a spring constant of 1.2 N/m. If the object is at rest when stretched 0.25 m, what is its total mechanical energy?

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. when the carts collide, they hook together. assume that positive momentum is to the right. which graph best represents the momentum of both carts over time, before and after the collision?

Which type of energy would have nothing to do with ironing clothes? a. heat b. chemical c. electrical d. mechanical

An ascending elevator, hanging from a cable, is coming to a stop. part a part complete identify all forces acting on the elevator from the list below. select all that apply. select all that apply. kinetic friction normal force tension weight static friction submitprevious answers correct part b draw a free-body diagram of the object. draw the vectors starting at the black dot. the location and orientation of the vectors will be graded. the exact length of your vectors will not be graded but the relative length of one to the other will be graded.
