Mar 01, 2016 · Added mass was first introduced by Dubua in 1776 then was expressed mathematically and exactly by Green in 1883 and Stokes in 1843 by expression of added mass of a sphere. Later many researchers generalized the notion of added mass to an arbitrary body moving in different regimes .

2. A wheel of mass 2 kg having practically all the mass concentrated along the circumference of a circle of radius 20 cm, is rotating on its axis with an angular velocity of 100 rad/s. The rotational kinetic energy of the wheel is (A) 4J (B) 70J (C) 400 J (D) 800 J. 3. A rod of length L is hinged from one end.

Nov 03, 2016 · A uniform 2 kg solid disk of radius R = 0.4 m is free to rotate on a frictionless horizontal axle through its center. The disk is initially at rest, and then a 10 g bullet traveling at 540 m/s is fired into it. If the bullet embeds itself in the disk at a vertical distance of 0.2 m above the axle, what will be the angular velocity of the disk?

Mass, velocity, and radius are all related when you calculate centripetal force. In fact, when you know this information, you can use physics equations to calculate how much force is required to keep an object moving in a circle at the same speed. You always have to accelerate an object toward the center of the […]

Mass and Weight The mass of an object is a fundamental property of the object; a numerical measure of its inertia; a fundamental measure of the amount of matter in the object. Definitions of mass often seem circular because it is such a fundamental quantity that it is hard to define in terms of something else.
