Asolid cylinder is mounted above the ground with its axis of rotation oriented horizontally. a rope is wound around the cylinder and its free end is attached to a block of mass 53.0 kg that rests on a platform. the cylinder has a mass of 275 kg and a radius of 0.360 m. assume that the cylinder can rotate about its axis without any friction and the rope is of negligible mass. the platform is suddenly removed from under the block. the block falls down toward the ground and as it does so, it causes the rope to unwind and the cylinder to rotate.(a)what is the angular acceleration of the cylinder? rad/s2(b) how many revolutions does the cylinder make in 5 s? rev(c)how much of the rope unwinds in this time interval? m

Aforce of 34n stretches a very light ideal spring 0.73 m from equilibrium, what is the force constant (spring constant) of the spring? (a) 47n/m (b) 38n/m (c) 53n/m (d) 25n/m

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
