Work done = F.d = F d cos(theta)
(A) W = (850 N) (5000 m) cos(0)
W = 4.25 x 10^6 J
(B) W = (850 N) (5000 m) cos35
W = 3.48 x 10^6 J
(c) W = m g d cos90
and cos90 = 0
W = 0

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)...

А D z Problem 3. Work done by gravity and change in gravitational potential energy In problem the box was moving in a horizontal direction, and therefore no work was done by gravity. Here, we will analyze a situation where the force of gravity has some component that points along the direction of the displacement, and therefore there is non-zero work done by gravity on the system of interest Consider a box of mass 10 kg, initially at rest, which...

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...
