Two men decide to use their cars to pull a truck stuck in mud. They attach ropes and one pulls with a force of 955 N at an angle of 28 with respect to the direction in which the truck is headed, while the other car pulls with a force of 1409 N at an angle of 23 with respect to the same direction.
What is the net forward force exerted on the truck in the direction it is headed?
Answer in units of N
Homework Answers
FNet^2 = F1^2 +F2^2 +2F1F2 cos theta
angle between F1 and F2 is 28-23 = 5 deg
sdo Fnet^2 = 955^2 + 1409^2 + 2* 155*1409 * cos 5
Fnet = 2361.833 N

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...

Your car is stuck in a mud hole. You are alone, but you have a long, strong rope. Having studied physics, you tie the rope tautly to a telephone pole and pull on it sideways at the midpoint, as shown. Find the force exerted by the rope on the car when the angle is 3.2 degree and you are pulling with a force of 395 N but the car does not move. Answer in units of kN. How strong must...

Part A Assume: in the y (vertical) direction: up is positive; in the x (north-south) direction: north is positive. Henry drives his car north at velocity 21.1 m/s, passing Annabelle, the stationary observer, standing on a street corner. If Annabelle sees rain falling straight down at constant velocity -45.3 m/s, find the speed of the rain, in m/s, according to Henry. Part B In the 19th century, barges were pulled by rope through the Erie Canal. Suppose two ropes of...

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...
