Two 400-mm diameter disks and a 240-mm diameter disk are joined 125 mm with respect to the axis of the spool. If a force P of 500 N is apploed to the spool through a cord that is wrapped around the cylinder, determine the acceleration aG of the mass center of the spool and the angular acceleration of the spool

Ascientist is tracking an object orbiting the sun that is found between mars and jupiter. in order to classify the object as an asteroid, it must be at least

Erosion of the beach is normally a slow process. however, in certain situations, large chunks of shore may wash out to sea. what could cause this to happen?

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?
