A force of 35.0 N acts on the block at the angle shown in the diagram. The block moves a horizontal distance of 10.00 m. To three significant figures, how much work is done by the applied force? Work = 300 Surface

Problem 8  A chain 25 feet long whose weight is 99 pounds is hanging over the edge of a tall building and does not touch the ground. How much work is required to lift the entire chain to the top of the building?

A child does 466 J of work while pulling a box from the ground up to his tree house at a steady speed with a light rope. The tree house is 4.8 m above the ground. What is the mass of the box? Use g = 9.8 m/s2   Calculate to one decimal

A 20 kg toddler tries hard to lift his mom’s 12 kg KSU book bag, applying a force of 25 N. The bag is heavy and he can’t begin to lift it. How much work does the helpful little guy do on the bag?

A 35 N applied force pushes a box to the right. The box moves 12 m. How much work was done by the applied force?

The figure below shows an overhead view of two horizontal forces pulling a box along the floor. How much work does each force do as the box is displaced 70 cm along the broken line. What is the total work done by the two forces in pulling the box this distance?

As is shown in the figure below a varying force acts on an object.  If Fmax=8.1 N and d = 8.8 N, determine the total work done on the object.  (Work is the area under the curve).

There are three different ways to get from location A to location E in the diagram below. In path 1, you take an elevator directly from location A straight up to location E. In path 2, you walk from A to B, climb a rope from B to C, then walk from C to E. In path 3, you walk from location A to D, then climb a ramp up to location E. The following questions focus on the work done on a 51 kg person by the Earth while following each of these paths. B = E A Taking the origin at location A, the coordinates of the other locations are: 7 B = (-3, 0, 0); 7c = ( -3, 12, 0 ) ; p = ( 39, 0, 0); > = { 0, 12, 0). (a) Path 1 (A to E): What is the displacement vector Ar for the path from A to E on the elevator? AT = (0,12,0) = D m (b) What is the gravitational force acting on the person along path 1, as a vector? (-0, -3.2e3,0) N X (c) What is the work done by the gravitational force of the Earth on the 51 kg person during the elevator ride from A to E? W1 F.Ar (d) Path 2 (A to B to C to E): What is…

A boy lifts a 30.0 N dragon 2.0 meters above the ground. How much work did the boy do on the dragon? What is the work?

A 57-kg cart slows down from a speed of 2.5 m/s and comes to rest due to friction. Use work-energy theorem to calculate the work done by the friction. Show work +5. Hint: Follow this guide, Calculate Initial Kinetic energy: K1 =  Calculate the Final Kinetic energy: K2 = Calculate the total work done W_tot = Enter the work done (include the sign if negative), rounded off to ONE decimal place
