Torque and Angular Acceleration Learning Goal: To understand and apply the formula τ= Iα to rigid objects rotating about a fixed axis. To find the acceleration a of a particle of mass m, we use Newton's second law. Fnet =ma, where Fnet is the net force acting on the particle. To find the angular acceleration a of a rigid object rotating about a fixed axis, we can use a similar formula: Tnet = Ia, where Tnet=∑T is the net torque acting on the object...

Your answer is partially correct. A wheel of radius 0.486 m is mounted on a frictionless horizontal axis. The rotational inertia of the wheel about the axis is 0.0240 kg-m. A massless cord wrapped around the wheel is attached to a 2.91 kg block that slides on a horizontal frictionless surface. If a horizontal force of magnitude - 3.52 N is applied to the block as shown in the figure, what is the angular acceleration of the wheel? Take the...

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...

To understand the two most
common procedures for finding torques when the forces and
displacements are all in one plane: the moment arm method and the
tangential force method. The purpose of this problem is to give you
further practice finding torques in two-dimensional situations. In
this case it is overkill to use the full cross product definition
of the torque because the only nonzero component of the torque is
the component perpendicular to the plane containing the problem.
