Academics

one block has a mass M = 500 g, the other has mass m = 460 g, and the pulley, which is mounted in horizontal frictionless bearings, has a radius of 5.00 cm. When released from rest, the heavier block falls 85.5 cm in 2.80 s (without the cord slipping on the pulley).

(a) What is the magnitude of the block's acceleration?

___ m/s^2

(b) What is the tension in the part of the cord that supports the heavier block?

___ N

(d) What is the magnitude of the pulley's angular acceleration?

___ rad/s^2

(e) What is its rotational inertia?

___ kg·m^2
