Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Answer the question in full details, thank you very much: A spherically symmetric object, with radius R = 0.70 m and mass M = 1.5 kg, rolls without slippingacross a horizontal floor, with velocity V = 3.0 m/s. It then rolls up an incline with an angle of inclinationAngle = 44 deg and comes to rest a distance d = 0.92 m up the incline, before reversing direction and rollingback down.

Mechanism shown consists of two 8-pound rods AB and CD. each and a 10 lab AD bar. When θ = 0 °, the rod AB rotates with a velocity angular of 2 rad / s. If a torque M = 15 lb * ft is applied to the rod CD and to the rod AD is applied a force P = 20 lb., calculate the angular velocity of the bar AB at the instant that θ = 40 °
A weight with mass mw=150 g is tied to a piece of thread wrapped around a spool, which is suspended in such a way that it can rotate freely. When the weight is released, it accelerates toward the floor as the thread unwinds. Assume that the spool can be treated as a uniform solid cylinder of radius R=4.00 cm and mass Ms=200 g. Find the magnitude ?a of the acceleration of the weight as it descends. Assume the thread has negligible mass and does not slip or stretch as it unwinds. Use ?=9.81 m/s2. Find the tension T in the thread.
A particle M1, weighing 2.4 Ibs, is tied to a thread and describes a circular path in a horizontal plane.

If M1 describes a uniform circular motion, with angular velocity w 3.1 rad/s, determine the radius R of the circumference in inches.

5) In ice figure skating, a couple execute a “top” (see picture). The centre of mass of the woman (58 kg) is situated 1.3 m from the axis of rotation which is vertical and passes through the centre of mass of the man (85 kg). They are spinning at a constant angular velocity equal to 3.1415 rad/s and the man and woman have moments of inertia, about their own centres of mass, equal to 1.6 and 2.5 kg.m2 respectively. Then the woman grabs the neck of the man. At this point, her moment of inertia decreases to 1.4 kg.m2 and her body centre of gravity is 0.9 m from the axis of rotation. Determine the new angular velocity. Hints: This is a conservation of angular momentum problem, and needs the parallel axis theorem to determine moments of inertia about the axis of rotation. The skaters are moving as one body with one angular velocity, but they each have their own moments of inertia given relative to their own CoMs. For the man, that’s fine…the axis they’re rotating about passes through his…
