Two people pull a 107 kg. boat from opposite sides of a narrow river with ropes that make a 60 degree angle with the velocity of the boat.. Each man pulls with equal force. The motion of the boat is opposed by a drag force from the water of 118 Newtons. If the boat accelerates to the right at a rate of 3.5 m/s2, with what force must each man be pulling his rope? Give your answer in Newtons.

two people pull as hard as they can on horizontal ropes attached to a boat that has a mass of 200 kg. If they pull in the same direction, the boat has an acceleration of 1.54 m/s squared to the right. If they pull in opposite directions, the boat has an acceleration of 0.516 m/s squared to the left. What is the magnitude of the force each person exerts on the boat? Disregard any other horizontal forces on the boat....

Two people pull as hard as they can on horizontal ropes attached to a boat that has a mass of 200 kg. If they pull in the same direction, the boat has an acceleration of 1.58 m/s^2 to the right. If they pull in opposite directions, the boat has an acceleration of 0.500 m/s^2 to the left. What is the magnitude of the force each person exerts on the boat?

Two canal workers pull a barge along the narrow waterway at a constant speed. One worker pulls with a force of 165 N at an angle of 32.5° with respect to the forward motion of the barge and the other worker, on the opposite tow path, pulls at an angle of 35.7° relative to the barge motion. Both ropes are parallel to the ground. Part 1 out of 2 (a) With what magnitude force should the second worker pull to...

Exercise 4 A block is attached to two ropes on opposite sides (m = 20 kg). One rope is wrapped around a bollard (angle of wrap a = 360°) and loaded by a force of S4 = 1000 N. The coefficient of static friction between the rope and the bollard is Moi = 0.2. The coefficient of friction between the block and the ground is Moz = 0.3. Determine the minimum force S3 that is required to keep the block...

QUESTION 7 A box is at rest on a horizontal, frictionless table. Horizontal force F1 points along the positive x-axis; when it is the only force acting on the box, the box accelerates at 6.75 m/s. Force F3 is also horizontal; it has magnitude 2.85F, and acts at an angle 22.6° to the direction of F1. If forces F1 and F3 act on the box at the same time, find the magnitude...

Renee is on Spring Break and pulling her 21-kg suitcase through the airport at a constant speed of 0.47 m/s. She pulls on the strap with 120 N of force at an angle of 38° above the horizontal. Assume the ground to be flat, Draw a FBD showing the forces on the suitcase. Find the acceleration of the suitcase. Determine the normal force experienced by the suitcase. Determine the total resistive force (friction) experienced by the suitcase. Find the coefficient...
