. You are using a rope to pull a sled at a constant velocity across level snow, with coefficient of kinetic friction 0.050 between sled and the snow. The sled is loaded with physics books, giving a total mass of 48 kg. (a) With what force should you pull with the rope horizontal? (b) Repeat for the rope at 30 ̊above horizontal.

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...

1) Tyrion is pulling a 30 kg sled loaded with ale across an ice lake. Assume the sled starts from rest and that it moves a distance of 10 m to the right. He pulls the sled to the right with a force of 300 N at angle of 30° above the horizontal. Once again, Cersei is trying to stop Tyrion from leaving and pulls on the sled horizontally to the left with a force of 100 N. Find the...

GOAL Apply the basic definitions of work done by a constant force. PROBLEM 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 of 1.20 102 N on the sled by pulling on the rope. (a) How much work does he do on the sled if the rope is horizontal to the ground (θ = 0° in the figure)...
