Base your answers to questions 54 to 58 on the information and diagram below.

A 3.0- kilogram mass is being moved at constant speed across a horizontal surface by a constant 6.0-newton horizontal force to the left.

54. what is the change in kinetic energy of the mass as it is moved from point M to point N?

55. Calculate the total work done in 2.0 seconds if energy is supplied at a rate of 10.0 watts?

56. what is the magnitude of the force of friction acting on the mass?

57. calculate the magnitude of the acceleration that would be produced by the 6.0-newton force if the surface the mass slides on was frictionless

58. calculate the gravitational potential energy of the 3.0-kilogram mass with respect to the horizontal surface if the ,ass was raised to a height of 4.0 meters?

A 3.0-kilogram mass is being moved at constant speed across a horizontal surface by a constant 6.0-newton horizontal force to the left. F = 6.0 N 3.0 kg 4.0 m Z 2
