Question:
A solid uniform disk of mass 21.0 kg and radius 85.0 cm is at rest flat on a frictionless surface. The figure(Figure 1) shows a view from above. A string is wrapped around the rim of the disk and a constant force of 35.0 N is applied to the string. The string does not slip on the rim.
Part A.
When the disk has moved a distance of 5.3m , determine how fast it is moving.
Express your answer using two significant figures.
Part B.
How fast it is spinning (in radians per second).
Express your answer using two significant figures.
Part C.
