![P4 4) [8 pts] A block of mass 10.5 kg on an inclined plane (angle 0-320) ls attached to a cord that is wrapped around a wheel of radius 14.0 cm as in the figure. As the block slides the wheel turns and the cord unwinds. The acceleration of the block down the incline (which is frictionless) is measured to be 2.50 m/s2. Assume the wheel spins without friction a) What is the tension in the cord? b) What is the angular acceleration of the wheel? c) What is the moment of inertia I of the wheel? 3.93 arrojn uhed](http://img.homeworklib.com/questions/aeca4eb0-46d1-11ea-b39d-41d9b25e64b3.png?x-oss-process=image/resize,w_560)

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...

The one I selected is incorrect. Please let me know why and
thank you.
Why should the block move at constant velocity (due to the pull of the hanging weight) when finding kinetic friction (procedure 2). Constant velocity means zero acceleration, means Tension = Friction force Because we cannot measure acceleration. if velocity is not constant, the tension in the string wil become zero. Because acceleration will add another force pulling the block (in addition to the tension in the...
