As seen from above, a playground carousel is rotating counterclockwise about its center on frictionless bearings. A person standing still on the ground grabs onto one of the bars on the carousel very close to its outer edge and climbs aboard. Thus, this person begins with an angular speed of zero and ends up with nonzero angular speed, which means that he underwent counterclockwise angular acceleration. The carousel has a radius of 1.50 m, an initial angular speed of 3.14 rad/s, and a moment of inertia of125 kgm2. The mass of the person is 48 kg. Find the final angular speed of the carousel after the person climbs aboard
a jet of engine on a test tube takes in 20kg of air per second at a velocity of 100m/s and burns 0.8kg of fuel per second.after compression and heating the exhaut gases are ejected
Describe Fresnel''s theory of optical rotation
Give any two methods of electric lines of force. Sketch them for an isolated positive point charge.
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
Like the centre of mass, the moment of inertia is a function of a body that is concurrent to its mass distribution. Moment of inertia gives a measurement of the resistance of a bod
