You are loading a refrigerator weighing 2135 N onto a truck, using a wheeled cart. The refrigerator is raised 1.06 m to the truck bed when it is rolled up a ramp. (Assume that there is no frictional force between the refrigerator and the ramp.) (a) Calculate the minimum work that must be done by the force you apply and the magnitude of the force if the ramp is at an angle with the horizontal of 45.0 degrees. minimum work =      force =   (b) Calculate the minimum work that must be done by the force you apply and the magnitude of the force if the ramp is at an angle with the horizontal of 10.2 degrees. minimum work   =    force=

A child on a sled is initially at rest on an icy horizontal surface. The sled is pushed until it reaches a final velocity of 6.60 m/s in a distance of 12.8 m. The coefficient of friction between the ice and runners of the sled is 0.200, and the weight of the child and the sled is 335 N. Find the work done by the force pushing the sled.

A block of mass 15.0 kg is pulled up from rest on a rough incline. The pulling force F =100.0 N that makes a 5.00° angle with the incline and the incline itself makes an angle of 10.0° with the horizontal. The coefficient of kinetic friction is 0.300, and the block is pulled 3.00 m on the incline. (a) How much work is done by the gravitational force on the block? (b) How much work is done by the 100.0-N force on the block? (c) How much work is done by the normal force? (d) Calculate work done by the friction force on the block. (e) What is the speed of the block after being pulled 3.00 m? F 5° 10°

A 4.5-kg block slides down a frictionless incline making an angle of 55.0° with the horizontal. (a) What is the total work done on the block when the block slides 1.4 m (measured along the incline)? (b) What is the speed of the block after it has slid 1.2 m if it starts from rest? m/s (c) What is its speed after 1.2 m if it starts with an initial speed of 1.6 m/s? m/s You can use the definition of work as the scalar product of a constant force and displacement to find the work done by each force acting on the block. Then use the work- kinetic energy theorem the find the speed of the block at any given location and for any initial kinetic energy it may have.

(a) find the tension in the rope. (b) if the block travels a distance of 4.5 m along the surface, what is the work done by the tension force from the rope? (c) find the work done by friction on the rock.

A shopper pushes a grocery cart 36.6 m on level ground, against a 13.1 N frictional force. The cart has a mass of 15.2 kg. He pushes in a direction 17.8º below the horizontal. If the initial velocity was 1.8 m/s, and final speed was 15.4 m/2. What is the work done by the pushing force in unit of Joule?
