For the adapted shuffleboard device in Prob 13.28, you decide to utilize an elastic cord instead of a compression spring to propel the puck forward. When the cord is stretched directly between points A and B , the tension is 20 N. The 425-gram puck is placed in the center and pulled back through a distance of 400 mm; a force of 100 N is required to hold it at this location. Knowing that the coefficient of friction is 0.3, determine how far the puck will travel.Reference to Problem 13.28:
A 5 kg box rests on a tabletop. On one side, it compresses a spring with a stiffness of 1000 N/m by 1 cm. If the friction force cancels out the force of the spring what must be the minimum coefficient of static friction between the box and table to keep the box from moving?

Four pets named Arjay, Baguilat, Cuh-ing, and Dabest play a pulling game with a rope as shown below. Arjay pulls strongly with 610.0 units of force (N). Baguilat pulls with a force of magnitude B = 200.0 N, and Cuh-ing pulls with aforce of magnitude C = 140.0 N. When Dabest pulls on the rope in such a way that his force balances out the resultantof the other three forces, the rope does not move in any direction. With how much force and in what direction mustDabest pull on the rope for the situation to happen? I need help in figuring out is the magnitude of Dabest's pulling force? the direction(use method 1: zero-degree reference line) of Dabest's pulling force and What is the direction(use method 2: geographical direction) of Dabest's pulling force?

A man is attempting to lift a crate with a double-pulley system, as shown. A single rope is routed from the ceiling, through the two pulleys, and to where the man pulls on it. The crate has mass m2 = 68 kg, and the man has m1 = 75 kg. He pulls downward on the rope with a force of magnitude F = 599 N. The pulleys are both massless and frictionless, and the rope is ideal. What is the magnitude, in newtons, of the tension force, T?What is the acceleration, in meters per squared second, of the crate?
