A desperate hiker has to think fast to help his friend who has fallen below him. Quickly, he ties a rope to a rock of mass m, and makes his way over the ledge (see the figure). m If the coefficient of maximum static friction between the rock and the ground is u, and the mass of the hiker is mh, what is the maximum mass of the friend, mf, that the rock can hold so the hikers can then...

How fast is the particle going after the force has entirely dissipated? [m/s]. 3.750 Marks for this submission: 3.0/3.0. Check A weight of mass 3.5 kg is attached to a rope that is wrapped around a freely rotating drum of radius 0.2 m. The drum has a mass moment of inertia of 0.52 kg.m2. (e-9.8m.s2) How many radians will the drum have travelled through when the weight drops to 2.1m? [rad] ion How fast will the weight be dropping when...

1. Dixon is a 43-year-old man with a family history of colon cancer. The physician has suggested that he perform a fecal occult blood test. However, when you discuss it with him he tells you that he is not interested because “there is nothing that can be done about colon cancer anyway.” He is referring to the fact that his father and his brother died of the disease. What should you say to him? 2. Jeffrey is a 15-year-old boy...

1. A ferris wheel has a radius of 12 m. The center of the ferris wheel is 14 m above the ground. When it is rotating at full speed the ferris wheel takes 10 s to make a full turn. We can track one seat on the ferris wheel. Let’s define t = 0 to be a time when that seat is at the top of the ferris wheel while the ferris wheel is rotating at full speed. (a) Write...

(non calculus based physics) Question 1 An Olympic weight lifter lifts an 1800 N set of weights from the ground to a vertical distance of 2.20 m above his head. Assuming he moves the weights at constant speed, how much work does the weight lifter do? Question 2 A 4.5 kg trunk, initially at rest, takes 2.0 s to slide 2.8 m down a rough 25° slope. Calculate: the work performed by the force of gravity. the amount of mechanical...
