Two crewmen pull a raft through a lock, as shown in the figure below. One crewman pulls with a force of F,- 129 N at an angle of 6, - 34.7° relative to the forward direction of the raft. The second crewman, on the opposite side of the lock, pulls at an angle of 6 2- 46.6°. With what force should the second

A 950-kg car pulls a boat on a trailer. ng Time: 03:25: (a) What force resists the motion of the car, boat, and trailer, if the car exerts a 1,232.5-N force on the road and produces an acceleration of 0.5 m/s²? The mass of the boat plus trailer is 500-kg. Number N (b) What is the force pulling the trailer if 80% of the resisting forces are experienced by the boat and trailer? (Hint: Treat the trailer as a separate system and solve a free body diagram.) Number N

In a two-dimensional tug-of-war, Alex, Betty, and Charles pull horizontally on an automobile tire at the angles shown in the picture. The tire remains stationary in spite of the three pulls. Alex pulls with force É of magnitude 201 N, and Charles pulls with force F c of magnitude 189 N. Note that the direction of F c is not given. What is the magnitude of Betty's force F Bif Charles pulls in (a) the direction drawn in the picture or (b) the other possible direction for equilibrium? Alex Charles 132° Betty

Block B in the figure weighs 711 N. The coefficient of static friction between the block and table is µs = 0.25; assume that the cord between B and the know is horizontal. Find the maximum weight of block A for which the blocks will be at rest.

A block is pulled by a string that makes an angle of 25º to the horizontal. If the mass of the block is 12.0 kg and the coefficient of friction is 0.25, what force would keep the block moving at a constant velocity?

A couple of hotel workers are trying to get a new couch into a suite. They soon realized that it wasn't going to fit through the main entrance, so they took it to the balcony of the room below. One of these guys pulled it straight upwards with 300N of force. The other guy has pressed the couch against a wall with an upwards force at an angle of 35o withrespect to the horizontal, as seen in the diagram. That pushing force has a total magnitude of 350 N.If the couch weighs 36 kilograms, and it is sliding up the wall with an acceleration of 1.5 m/s2, what is the coefficient of kinetic friction between the couch and the wall?

Two blocks of mass M1 and M2 are connected by a massless string that passes over a massless pulley as shown in the figure. M1 has a mass of 8.75 kg and rests on an incline of M2 01 = 63.5°. M2 rests on an incline of 02 33.5°. Find the %3D M, mass of block M2 so that the system is in equilibrium (i.e., not accelerating). All surfaces are frictionless. 0, Figure is not to scale. kg M2 =

A father gives his son a ride by pulling on a sled. The father pulls the sled across the ground with a force F =75.0 N, directed 30° above %3D (Consider Newton's Laws and the forces/components} the horizontal (as shown). The combined mass of his son and sled is 44.0 kg. What normal force does the ground exert on the sled? O 394 N 485N O 270 N N 69
