A handbrake is applied to a rotating wheel, initially moving counterclockwise, causing it to slow down with a constant angular acceleration of magnitude
5.20 rad/s2.
Immediately after the handbrake is applied, the wheel rotates through 57.9 rad during a 4.00 s time interval. What is the angular speed (in rad/s) of the wheel at the end of this time interval?
Homework Answers
Concept – first find the initial angular velocity of the wheel using rotational kinematics. Use the initial angular velocity to find the final angular velocity.

A counterclockwise torque is suddenly applied to a rotating shaft with a moment of inertia of 5 kg•m2 . The shaft was initially at rest (zero speed). If the applied torque causes the shaft to rotate at a constant angular acceleration of 1.5 rad/s2 , considering zero viscous damping: a) Calculate the applied torque. b) Calculate the angular speed of the shaft after 5 seconds in radians per second. c) Express the speed in revolutions per minute.
