A playground merry-go-round has diameter 6.20 m and a mass of 180 kg. It is a solid disc pivoted around a vertical axle through its center. Its moment of inertia about the axle might be calculated using the formula: I=1/2 MR2. The disk turns with negligible friction. You apply a 34.0 N force tangentially to the edge of the merry-go-round for 12.0 s. (a) If the initial angular speed of the merry-go-round is 2.00 rev/min, what is its angular speed after this 12.0 s interval? (b) What is the tangential speed of a point on the edge? (c) Calculate the total angle covered by the point on the edge

You apply a 34.0 N force tangentially to the edge of the merry-go-round for 12.0 s.  (a)	If the initial angular speed of the merry-go-round is 2.00 rev/min, what is its angular speed after this 12.0 s interval?  (b)	What is the tangential speed of a point on the edge? (c)	Calculate the total angle covered by the point on the edge
