A shopper pushes a grocery cart 39.25 m on level ground, against a 37.06 N frictional force. The cart has a mass of 19.79 kg. He pushes in a direction 24.67º below the horizontal. If the initial velocity was 1.78 m/s, and final speed was 16.88 m/2. What is the work done by the pushing force in unit of Joule?
In a gravity escape system (GES), an enclosed lifeboat on a large ship is deployed by letting it slide down a rampand then continue in free fall to the water below. Suppose a 4970-kg lifeboat slides a distance of 5.00 m on a ramp, dropping through a vertical height of 2.50 m. How much work does gravity do on the boat?
A 65g Frisbee is thrown from a point 1.20 m above the ground with a speed of 12.00 m/s. When it has reached a height of 2.70 m, its speed is 10.4831 m/s. How much work was done on the Frisbee by its weight?
5. A person pulls an object of mass 40 kg as far as 20 m above a flat floor at a constant speed. The force used is directed 370 upwards horizontally. The coefficient of kinetic friction of the object with the floor is 0.20. Determine the work by the person, the work by the frictional force, and the total work on the object.
2. A 9 kg box is raised by a crane to a height of 5 m from the ground. From rest it slides down a frictionless incline, 30° from the horizontal. Then it slides on a horizontal floor where a constant frictional force is introduced. The block is brought to rest at point B, which is 20 m to the right of point A. a) What is the work done on the 9 kg block by the crane and by gravity? b) What is the speed of the 9 kg block by the time it reaches point A? c) What is the work done by the frictional force on the two blocks as they come to a stop?
A man pushes an 46-N crate a distance of 62 m upward along a frictionless slope that makes an angle of 30 with the horizontal. The force he exerts is parallel to the slope. If the speed of the crate increases at a rate of 2.2 m/s, then the work done (in J) by the man is.
4. A 6.00-kg watermelon is dropped from rest from the roof of a 30.0-m-tall building and feels no appreciable air resistance.

1. A jeep with mass of 2000 kg is going 18 m/s at the bottom of a hill that is 50.0m high. When it reaches the top, it is travelling at 10m/s. (a) what is the total work done by all forces (the jeep engine, the mud, gravity, etc) as it ascends the hill? (b) What is the minimum work required by engine of the jeep if only the engine and gravity are doing work (if there is na friction, forces from mud, etc)?

6. One end of a light inextensible string is attached to a block. The string is used to pull the block along a horizontal surface with a speed of 2 m s−1. The string makes an angle of 20° with the horizontal and the tension in the string is 25 N. Find the work done by the tension in a period of 8 seconds.
2. A tow truck pulls a car 5.00 km along a horizontal roadway using a cable having a tension of 850 N. (a) How much work does the cable do on the car if it pulls horizontally?
