Your relative from abroad sent your family a balikbayan box. Since you know that the laws of motion will help you move the box easily, you volunteered to bring it inside your house. You have two options: (a) pulling the box from a rope that makes an angle with the surface or (b) by pushing the box with a force that makes the same angle (but pointing downwards) with the surface. Which choice will you choose? Will the angle matter?

A person pulls at an angle of 0 = 34.0° on three connected crates of masses m¡ = 25.0 kg, m2 = 18.0 kg, and Pull m3 = 15.0 kg over a smooth horizontal floor, as shown in A В the figure. The crates are connected to each other by m, m, m3 identical massless, horizontal strings A and B, each of which can support a maximum tension of 45.0 N before breaking. What is the magnitude F, of the largest pulling force that can be exerted without breaking either of the strings?
Displayed to the right are two carts connected by a cord that passes over a small frictionless pulley. Each cart rolls freely with negligible friction. Consider the mass of the cart to be m1 = 18.1 kg and the angle the first cart sits on to be θ1 = 37.5°, while the mass of the second cart as m2 = 24.1 kg and the angle it sits on to be θ2 = 50.5°.a = 1.759m/s^2 What is the equation for tension in regards to the rope coming from the second block? Answer in terms of the mass of the block m2, the acceleration due to gravity g, the angle θ2, and the acceleration of the blocks found previously a. Calculate the tension in the rope T in newtons.
Using the same force table that you used, a student was given two forces and asked to find a single force that would produce equilibrium with the two forces. The two forces were given by providing one of the components and the angle the force made with the positive x- axis. The two forces were as follows: Force 1: ?? = −2.70 ?; ? = 220.0 degreees Force 2: ?? = 3.20 ?; ? = 60.0 degrees (a) For each force, calculate the magnitude of the force and the mass required to produce it. (b) Calculate the mass and its angle of application to produce equilibrium with these two forces. Please specify your angle as counterclockwise positive with respect to the positive x-axis.

THE ILLUSTRATION IS ATTCHED The helicopter view in the figure below shows two people pulling on a stubborn mule. (Take F1 = 147 N and F2 = 63.0 N) An illustration shows the helicopter view of a mule being pulled along a forked road in two directions by two men. An x y coordinate system is overlaid on the image, with the origin at the mule's nose, and the mule facing in the positive y-direction. The man on the right is pulling the mule toward the right-side forked road with a force F1. This force vector makes an angle of 60.0° with the horizontal drawn right in front of where the mule is standing. The man on the left is pulling the mule toward the left-side forked road with a force F2. This force vector makes an angle 75.0° with the horizontal. (a) Find the single force that is equivalent to the two forces shown. magnitude_____ direction _____ ° counterclockwise from the +x-axis (b) Find the force a third person would have to exert on the mule to make the net force equal to zero.…

A makeshift sign hangs by a wire that is extended over an ideal pulley and is wrapped around a large potted plant on the roof as shown in Figure P6.10. When first set up by the shopkeeper on a sunny and dry day, the sign and the pot are in equilibrium. Is it possible that the sign falls to the ground during a rainstorm while still remaining connected to the pot? What would have to be true for that to be possible? FIGURE P6.10 Problems 10 and 11.
