Pete slides a crate up a ramp with constant speed at an angle of 23.2 ◦ by exerting a 137 N force parallel to the ramp. How much work has been done against gravity when the crate is raised a vertical distance of 2.97 m? The coefficient of friction is 0.26. Answer in units of J.

Anonzero net force acts on a particle and does work. which one of the following statements is true? the kinetic energy of the particle changes, but the speed of the particle does not change. the kinetic energy of the particle does not change, but the speed of the particle does change. the kinetic energy of the particle changes, but the velocity of the particle does not change. the kinetic energy and the speed of the particle change, but the velocity of the particle does not change. the kinetic energy, speed, and velocity of the particle change.
