A farmer attaches a tractor to a sled filled with firewood with
chains at an agle of 33.5 0 as shown. If the tractor exerts a
constant force of 5125 N above the horizontal and pulls it a
distance of 20.0 m, find the work (J) done on the sled, neglecting
friction.

A sled is being pulled across rough snow by a rope at an angle of 20° to the horizontal. The sled has a mass of 31 kg and the passenger has a mass of 22 kg. The sled is moving at a steady 0.63 m/s. The force on the rope is 65 N. A. Draw a free body diagram for the sled and passenger as one thing. B. What is the normal force on the sled? C. What is the...

An Eskimo returning from a successful fishing trip pulls a sled loaded with salmon. The total mass of the sled and salmon is 50.0 kg, and the Eskimo exerts a force on the sled by pulling on the rope. The coefficient of kinetic friction between the sled and the ground is 0.200. (a) The Eskimo pulls the sled 6.00 m, exerting a force of 1.15 102 N at an angle of θ = 0°. Find the work done on the...

Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....

A loaded penguin sled weighing 64 N rests on a plane inclined at 20° to the horizontal. Between the sled and the plane the coefficient of static friction is 0.20, and the coefficient of kinetic friction is 0.17. (a) What is the minimum magnitude of the force , parallel to the plane, that will prevent the sled from slipping down the plane? ___N (b) What is the minimum magnitude F that will start the sled moving up the plane? ___...

A loaded penguin sled weighing 80 N rests on a plane inclined at
20° to the horizontal. Between the sled and the plane the
coefficient of static friction is 0.26, and the coefficient of
kinetic friction is 0.17.What is the minimum magnitude of the force F, parallel to the
plane, that will prevent the sled from slipping down the

the plane?What value of F is required to...
A sled weighing 60.0 N is pulled up a snowy hill inclined at 10 degrees to...
A sled weighing 60.0 N is pulled up a snowy hill inclined at 10 degrees to the horizontal at a constant speed so that the coefficient of kinetic friction between sled and snow is 0.070. A penguin weighing 70.0 N rides on the sled. If the coefficient of static friction between penguin and sled is 0.950, find a). the force of friction between the sled and the snow, b). the force of static friction between the penguin and the sled,...

You pull a your friend along in a sled (combined mass is 65 kg), by pulling the rope at an upward angle of 20 degrees with respect to the ground with enough force to keep the sled moving at a constant velocity of <3,0, 0> m/s. The coefficient of kinetic friction between the ground and the sled is 0.15. (a) Draw a force diagram for the friend/sled system. (b) Once you get to constant velocity, you pull the sled 15...

As shown in the figure, a 25 kg block is being pulled by a force F = 220 N up along a rough incline. The coefficient of kinetic friction between the block and the incline is μk = 0.30. The block is pulled through a distance of 23.0 m. (c) Calculate the work (in Joules) done by the pulling force F. Pay attention to the angle in the work formula and the sign of work. (d) Calculate the work (in...
