6.38 Leg Presses. As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. When you push the platform, you compress the springs. You do 80.0 J of work when you compress the springs 0.200 m from their uncompressed length. (a) What magnitude of force must you apply to hold the platform in this position? (b) How much additional work must you do to move the platform 0.200 m farther, and what maximum force must you apply?

9. A man pushes an 80-N crate up a frictionless slope that makes an angle of 30° with the horizontal. The man was able to push it to a distance of 5.0Om along the slope with a force parallel also to the slope. However the speed of the crate decreases at a rate of 1.5 m/s?. The work being done by the man is: A. -200 J В. 61J С. 140 J D. 200 J 14. A 6.0-kg block is released from rest 80 m above the ground. When it has fallen 60 m its kinetic energy is approximately: A. 4800 J В. 3500J C. 1200 J D. 120 J
A 5.8 kg body is at rest on a frictionless horizontal air track when a constant horizontal force F acting in the positive direction of an x axis along the track is applied to the body. A stroboscopic graph of the position of the body as it slides to the right is shown in the figure. The force F is applied to the body at t = 0, and the graph records the position of the body at 0.50 s intervals. How much work is done on the body by the applied force F between t = 0 and t = 1.0 s? t = 0 -0.5 s -1.0 s -1.5 s -2.0s 0.4 x (m) 0.2 0.6 0.8

A 12.0 kg box is given an initial push that starts it sliding across the floor. It eventually comes to a stop. If the box has an initial velocity of 3.5 m/s, how much work is done by friction to cause it to come to a stop? (Yes, you are correct, you do not know the coefficient of friction.)
Several children are on a sled pulled by a four-wheeler across a level snow-covered field. The sled is moving at a constant speed of 9.25 m/s, and the tow rope (parallel to the ground) makes an angle of 35.0°, with respect to the velocity of the sled (see the figure below). a 35.0⁰ 1170 If the tension in the rope is 49.0 N, determine the work done (in J) on the sled by the tension in the rope in 10.5 s.

The force F = (5.89 N)i + (7.5 N)j acts on a particle as it moves along a straight line from Cartesian coordinate (1.77 m, 1.31 m) to (8.81 m, 8.03 m). 1. What is the work done, in joules, by the force?
A bungee jumper makes a stunt jump in a jumping platform 8.57 m from above a height. The jumper weighs 130 N. If the jumper falls to within 83.38 m of the bottom of the height, how much work is done by the bungee cord on the jumper during his descent? Ignoring air resistance. No unit is required for the final answer.
