Please answer that question ASAP
1. Consider a disc and hoop both of the same mass M, radius R and thickness I. a) Explain why one of these objects has a larger moment of inertia (about an axis through the center of mass and perpendicular to the plane of the object) than the other. What effect does the thickness I have on the rotational inertia? b) Explain how the rotational inertia of the disc may be obtained by adding the...

Learning Goal: To learn the definition andapplications of angular momentum including its relationship totorque. By now, you should be familiar with the concept ofmomentum, defined as the product of an object's mass andits velocity: . You may have noticed that nearly every translationalconcept or equation seems to have an analogous rotationalone. So, what might be the rotational analogue of momentum? Just as the rotational analogue of force , called thetorque , isdefined by the formula , the rotational analogue of...

Problem 1: A wheel starts from rest and rotates with constant angular acceleration and reaches an angular velocity of 32.0 rad/s in 4.00 s. (a) What is the magnitude of the angular acceleration of the wheel? (b) Through what angle does the wheel rotate in these 4.00 s? Problem 2: An automobile traveling at 90.0 km/hour, has tires of 75.0 cm diameter. (a) What is the angular velocity of the tires about the axis of rotation? (b) If the car...

10*) The Sun has approximate radius 7×108 m, and rotates around
its axis once every 27 days. a) Find its angular velocity in rad/s,
and (assuming it is a uniform sphere) write a formula for its
angular momentum expressing it in terms of its mass M (you do not
need to substitute a value for M). b) Suppose the Sun were to
collapse to a neutron star, which is a much denser state, without
losing any mass and without being...

Please answer ALL parts.
A phonograph turntable driven by an electric motor accelerates at a constant rate (i.e., constant angular acceleration) from 0 to 33.33 revolutions per minute in 2 minutes. The turntable is a uniform disc of mass 1.5 kg and radius R = 13 cm, as indicated in the figure. The radius of the driving wheel is r = 2.0 cm. What is the torque required to drive the turntable at this angular acceleration? If the driving wheel...
