A block with mass m1 m1=2.30 kg rests on a frictionless table. It is connected with a light string over a pulley to a hanging block of mass m2 m2=4.30 kg. The pulley is a uniform disk with a radius of 3.30 cm and a mass of 0.500 kg (the figure below). 1) Calculate the acceleration of each block. (Express your answer to three significant figures.) 2)Calculate the tension in the x-direction (horizontal part of string). (Express your answer to three significant figures.) 3)Calculate the tension in the y-direction (vertical part of string). (Express your answer to three significant figures.) 4)How long does it take the blocks to move a distance of 2.45 m? (Express your answer to three significant figures.) 5)What is the angular speed of the pulley at this time? (Express your answer to three significant figures.)
