- On a frictionless surface, a man wants to move forward, can it move forward? Explain• Mention 3 physical variables that are represented by vectors: a. b. C.Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo spelled backwards). It is the very latest in home safety and so easy to use!If your building is on fire, simply reach out and grab the cord on the OyOy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass M = 94.0 kg and is shaped like a cylinder of radius R = 0.810 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0800 meters. The cord is wound around the small shaft and this is the secret to your low velocity. We will use the approximation that the shaft is of negligible mass compared to the total. This means that you can treat the entire OyOy as though it is a solid cylinder with mass M and radius R. Imagine that a customer of mass m = 85.5 kg is using the OyOy and begins his decent from an initial height of y0 = 11.20 meters.Determine all the following:The…

Please finish the vector equations in the table below, Vector i i Fuet 20 -40 a Vo -4 -6 V D2. Let a = (2₁0) b = (-3,-3) and c = (0₁-4) a) Draw the free body diagram of these Vectors. b) find u = a + b + Č 13 c) Draw u on your free body diagram
- Week 3 #9(2) The box with M = 40kg shown below is being pulled by two pulleys exerting forces F₁ = 400 N (0₁ = 60°) and F₂ = 200 N (0₂= 15°) up an incline with an angle 0₁ = 30°. If the uk = 0.15. What is the acceleration of the box? Would the F₁ or F₂ be enough alone to pull the box up if the other pulley would stop working?q7 help please
