Two objects, of masses m₁ = 470.0 g and m₂ = 535.5 g, are connected by a string of negligible mass that passes over a pulley with frictionless bearings. The pulley is a uniform 55.0-g disk with a radius of 4.32 cm. The string does not slip on the pulley.

(a) Find the accelerations of the objects.
m/s²

(b) What is the tension in the string between the 470.0-g block and the pulley? (Round your answer to four decimal places.)
N

What is the tension in the string between the 535.5-g block and the pulley? (Round your answer to four decimal places.)
N

By how much do these tensions differ? (Round your answer to four decimal places.)
N

(c) What would your answers be if you neglected the mass of the pulley?
