In order to get full credit, you need to show all your work.

A force Fx = cx3 (c = 3.0 N/m3) acts on an object with mass 40 kg that is sliding along a rough horizontal floor (x-axis) with coefficient of kinetic friction of 0.2.

  1. What is the work done by the force Fx on this object as it slides from x1 = 0.0 m to x2 = 6.0 m?
  2. What is the work done by the force of friction on this object as it slides from x1 = 0.0 m to x2 = 6.0 m?
  3. If the object has a kinetic energy of 1300 J at x2 = 6.0 m, what was its kinetic energy at x1 = 0.0 m?

A single conservative force acts on a 5.00 kg particle. The equation Fx = (2x + 4) N describes this force, where x is in meters. As the particle moves along the x axis from x = 3.00 m to x = 7.00 m, calculate the following. (a) the work done by this force on the particle J (b) the change in the potential energy of the system J (c) the kinetic energy the particle has at x = 7.00...

After a hard day's work, you return home and decide to clean your apartment. In order to do so, you need to move your bed which has a mass of 110 kg. You exert a horizontal force of 270 N and your bed refuses to move. You roll up your sleeves and keep pushing until you exert a horizontal force 540 N. The bed slides a little but now you are exhausted and stop pushing. You have an aha! moment...

Learning Goal: To understand how to apply the law of conservation of energy to situations with and without nonconservative forces acting. The law of conservation of energy states the following: In an isolated system the total energy remains constant. If the objects within the system interact through gravitational and elastic forces only, then the total mechanical energy is conserved. The mechanical energy of a system is defined as the sum of kinetic energy K and potential energy U. For such...

PLEASE ANSWER ALL PARTS AND SHOW ALL WORK! In this section, all collisions will be completely elastic – that is, the total kinetic energy of the system will be constant throughout. Also, the collisions are entirely one-dimensional, with all motion taking place in either the northward or southward direction. The setting: a room with a frictionless floor. A block of mass 1 kg is placed on the floor and initially pushed northward, whereupon it begins sliding with a constant speed...
