Two objects, of masses m1= 500 g and m2 = 510 g, are connected by a string of negligible mass that passes over a pulley with frictionless bearings. The pulley is a uniform 50.0 g disk with a radius of 4.00 cm. The string does not slip on the pulley. Find the accelerations of the objects. (b) What is the tension in the string between the 500-g block and the pulley? What is the tension in the string between the 510-g block and the pulley? By how much do these tensions differ?
