The drive chain in a bicycle is applying a torque of 1.550 N- m to the wheel of the bicycle. The wheel has a moment of inertia of 0.150 kg • m?. What is the angular acceleration of the wheel?my answer was 10.33 rad/s^2? Can we also write the answer as 10 rad/s^2?

The body in the figure is pivoted at O. Three forces act on it in the directions shown: FA = 9.30 N at point A, 5.40 m from O; FB = 13.0N at point B, 2.90 m from O; and Fc = 18.0 N at point C, 2.90 m from O. Taking the clockwise direction to be negative, what is the net %3D torque about O? 135° A C 160° 90 FA Units Number i

A simple pendulum consists of a small object of mass 3.0 kg hanging at the end of a 2.0-m-long light string that is connected to a pivot point. (a) Calculate the magnitude of the torque (due to the force of gravity) about this pivot point when the string makes a 8.0° angle with the vertical. N.m (b) Does the torque increase or decrease as the angle increase? increase O decrease Explain.

A skater spins about a fixed point on the ice. She begins with her arms extended and an initial angular velocity wo. She then pulls her arms in to her body. After her arms are pulled to her body, she spins with an angular velocity final ,wf . Throughout the time she is spinning, no external forces are acting in the horizontal plane. How do the magnitudes of the initial and final angular velocities compare? OA. Wo > Wf OB. WO = wf w0 < wf OE. ооо оо
