- A heavy box is pulled by a rope on a horizontal surface. (a) Assume that there is no frictional force between the box and the surface. If the tension force in the rope is 240 N and the box moves by the distance of 5.6 m in 2.9 s, what is the power output of the work done by the tension force? (b) Assume that the surface is rough and there is frictional force between the box and the surface. If the box moves at the constant speed of 0.31 m/s when the tension force is 240 N, what is the power output of the work done by the tension force?A box of mass 4.0 kg is accelerated from rest across a floor at a rate of 2.0 m/s^2 for 9.0 s . a.)

- 3) The meaning of the word "WORK" is quite different in physics from its everyday usage. Give an example of an action a person could do that "feels like work" but that does not involve any work as we've defined in this chapter. Support your reasoning with equations/data.Calculate the work done by friction as a 3.7 kg box is slid along a floor from point A to point B in the figure along paths 1, 2, and 3. Assume that the coefficient of kinetic friction between the box and the floor is 0.19. (Figure 1) Enter your answers numerically separated by commas. Express your answers using two significant figures. W1,W2,W3= ______ JIn the figure shown if A=5.0, B=8.0 and x=30degrees, determine the scalar product of the two vectors shown.
