Explanation 1) Concept: We use the concept of conservation mechanical energy. Using gravitational potential energy and rotational kinetic energy we can write the equation for angular velocity . We can find the inertia of the system, and using that inertia in angular velocity equation we can find the answer. 2) Formulae: i) M . E = m g h + 1 2 I ω 2 ii) I = M R 2 3) Given: Length of the rod is L = 0.600 m 4) Calculations: Centre of the mass of the system is at L 2 and total mass of the body is M, when the system moves down the gravitational potential energy of the system decreases by - M g L 2 we can write the equation of mechanical energy as, M . E = - M g L 2 + 1 2 I ω 2 Initially kinetic energy of the system is zero, we get, 0 = - M g L 2 + 1 2 I ω 2 M g L 2 = 1 2 I ω 2 ω 2 = M g L I ω = M g L I We can find the inertia of the system about axis passing through one of the leg of H

Angular Momentum

The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…

Moment of a Force

The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…

Part A ■Review The uniform 150-lb stone (rectangular block) is being turned over on its side by pulling the vertical cable slowly upward until the stone begins to tip. (Figure 1) If it then falls freely (T = 0) from an essentially balanced at-rest position, determine the speed at which the corner A strikes the pad at B. The stone does not slip at its corner C as it falls. Suppose that height of the stone is L = 1.2 ft.

Consider the circuit shown in the figure. The battery has emf ε = 69 volts and negligible internal resistance. The inductance is L = 0.4 H and the resistances are R 1 = 12 Ω and R 2 = 9.0 Ω. Initially the switch S is open and no currents flow. Then the switch is closed. After leaving the switch closed for a very long time, it is opened again. Just after it is opened, what is the current in R 1?
