# Inertia problem

Not what you're looking for?

In Fig. 11-42, 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 81.5 cm in 2.90 s (without the cord slipping on the pulley).

(a) What is the magnitude of the block's acceleration? _______m/s2

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

(c) What is the tension in the part of the cord that supports the lighter block? _______N

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

_______rad/s2

(e) What is its rotational inertia?

_______kg m2

Step 1.

The general equation relating constant acceleration a, to position y, time t, and initial velocity vo, is:

(1) y= vo t + .5 a t^2 in which vo=0.

Step 2.

In (1), knowing y and t and vo, you should substitute knowns to find:

(a) ANSWER acceleration (2) a= .194 nt/kg or .194 m/sec^2
