(a) What is the angular speed (rad/s) of the wheel just after the bullet leaves it? (b) How much kinetic energy (J) was lost in the collision?
Physics
A bullet with a mass m = 4:83 g and initial speed of 330 m/s passes through a wheel which is initially at rest as in the The wheel is a solid disk with mass M = 2.29 kg and radius R = 1.:6 cm. The wheel rotates freely about an axis through its center and out of the plane shown...

A long thin rod of mass M = 2:00 kg and length L = 75:0 cm is free to rotate about its center as shown. Two identical masses (each of mass m = .403 kg) slide without friction along the rod. The two masses begin at the rod's point of rotation when the rod is rotating at 10....

In order to change the angular momentum of an object, it is necessary to apply a. a net force to the object. b. a net torque to the object. c. a centripetal acceleration to the object. d. both a net force and a net torque to the object. We have three vectors, labeled A, B, and...

an (2a-4)=2(a-2) or -2(2-a) which will cancel out your 2-a, then do the same for the 2a+4, and this should give you your answer

A star with the same mass and diameter as the sun rotates about a central axis with a period of about 29.2 days. Suppose that the sun runs out of nuclear fuel and collapses to form a white dwarf star with a diameter equal to that of the earth. Assume the star acts like a solid...
