Two crewmen pull a raft through a lock, as shown in Figure below. One crewman pulls with a force of 130 N at an angle of 34° relative to the forward direction of the raft. The second crewman, on the opposite side or the lock, pulls at an angle of 45°. With what force should the second crewman pull so that the net force of the two crewmen is in the forward direction? 45 130 N

A woman exerts a horizontal force of 145 N on a box with a mass of 37.2 kg If the box doesn't move, what's the magnitude of the static friction force (in N)?

Question 2 To give a 22-kg child a ride, two teenagers pull on a 3.5- kg sled with ropes, as indicated in the figure (Figure 1). Both teenagers pull with a force of 55 N at an angle of 35° relative to the forward direction, which is the direction of motion. In addition, the snow exerts a retarding force on the sled that points opposite to the direction of motion, and has a magnitude of 57 N. You may want to review (Pages 134 - 136) .

Block A has a mass of 10.0 kg, block B has a mass of 11.0 kg, block C has a mass of 12.0 kg. If there is an applied force of 18.0 N, find the magnitude of the tension in the rope between blocks A and B Ignore friction. (Input your answer with 1 decimal place) A B T

A man pulls a cement block with a force of 450N using a rope that makes an angle of 35.0 degrees above the horizontal. What is the x-component of his pulling force?

Please include a diagram.

A certain orthodontist uses a wire brace to align a patient's crooked tooth as in the figure below. The tension in the wire is adjusted to have a magnitude of 28.0 N. Find the magnitude of the net force exerted by the wire on the crooked tooth.

Three boxes, A, B, and C, are placed on a frictionless surface as shown in the diagram below. B A If you push on box A with a force of 8.25 N, find the contact force (in N) between each pair of boxes. Here mA = 7.10 kg, mg = 4.50 kg, and mc = 1.50 kg. contact force between A and B N contact force between B and C N

Braces are used to apply forces to teeth to realign them. Shown in this figure are the tensions applied by the wire to the protruding tooth. T = 27.5 N What is the magnitude of the net force that is exerted on the tooth (in N) if the tension in the wire is 27.5 N?
