A book starts at rest.  If Fa=20.0 N, the mass of the book is 3.00 kg, θ=30º and d = 6.2 m, determine the speed of the book at the end of the displacement.  Use g = 10 Kg/m.  Hint:  Determine the net force (applied force net gravity) in the direction of displacement and then multiply by the displacement.  Use the work energy theorem to get speed.

With a starting velocity of 2 m/s to the right, you drag a 30.0 kg box for 4 meters. Your force is 200.0 N and the box's final velocity is 1.15 m/s to the right. Friction does -840 J of work.  What is the force of friction?

Suppose the ski patrol raises a rescue sled and victim, having a total mass of 85.0 kg, up a ? = 62.0° slope at constant speed, as shown in the figure. DO NOT USE THE ANGLE SHOWN IN THE FIGURE! USE THE ANGLE IN THE PROBLEM STATEMENT ABOVE. The coefficient of friction between the sled and the snow is 0.130.   Calculate the normal force on the sled (in N).   Calculate the work done (in J) by the force of friction as the sled moves 30.0 m up the hill. (Hint: Think about the direction of the friction force. Should it be different than the direction shown in the figure?).   Calculate the work done (in J) by the tension force in the rope on the sled over this distance. Calculate the work done (in J) done by the force of gravity on the sled over this distance.

The concepts in this problem are similar to those in Multiple-Concept Example 4, except that the force doing the work in this problem is the tension in the cable. A rescue helicopter lifts a 82.3-kg person straight up by means of a cable. The person has an upward acceleration of 0.668 m/s² and is lifted from rest through a distance of 9.10 m. (a) What is the tension in the cable? How much work is done by (b) the tension in the cable and (c) the person's weight? (d) Use the work-energy theorem and find the final speed of the person. t tou
