10 uyles A small block B is placed on block A of mass 5 kg and length 20 cm. A constant horizontal force of 10 N is applied on block A. If all the surfaces are assumed frictionless and block B is at the right end of block A, then time in which block B separates from A is BI А 10 N​

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?
