An object of mass M is used to provide tension in a 4.5-m-long string that has a mass of 0.272 kg, as shown in the figure below. A standing wave that has a wavelength equal to 1.5 m is produced by a source that vibrates at 30 Hz. 1) Calculate the value of M. (Express your answer to two significant figures.)
Your daredovil friends attach a rope to a 140 kg sled that rests on a frictionless icy surface. The rope extends horizontally to a smooth dead tree trunk lying at the edge of a Another person attaches a 30 kg rock at the end of the rope after it passes over the tree trunk and then releases the rock the rope is initially lout. There is no friction between the rope and the tree trunk Determine the acceleration of the...
