Homework Answers
The total force acting on sled is normal and friction force and the force that is acting on the block.
Here the friction force will be equal to the force applied but in opposite direction. Because this is static friction which is acting.
So work done by friction = force x displacement
- 1.1x 100 x 4.9 =539j
Total work done will be sum of both. So it will be zero.
Also Since there is no change in the velocity of sled so change in energy is zero so work done is zero.

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 father pulls a sled and child with a force of 220 N by a rope making an angle of 20 degree with the horizontal. If the sled and child has a mass of 47 kg, to the nearest hundredth of 3 m s what is the acceleration of the sled and child? Two crates of mass 75 kg and 110 kg arc in contact and rest on a rough horizontal surface. A 620 N force is exerted on the...

A man pulls a 10-kg sled 59 meters along an angled hill with a force of 108 N, which elevates the man 30 meters above the bottom of the hill. The man then hops on his sled and slides from rest to the bottom of the hill back along his 59 meter path, during which a 148 N frictional force acts upon his sled. How much work in Joules does the man do against friction in pulling the sled up...

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.
