A light rod of length l= 1.00 m

rotates about an axis perpendicular

to its length and passing

through its center as in

Figure P8.51. Two particles of

masses m_{1} = 4.00 kg and m_{2} =3.00 kg are connected to the

ends of the rod. (a) Neglecting

the mass of the rod, what is the

system’s kinetic energy when

its angular speed is 2.50 rad/s?

(b) Repeat the problem, assuming

the mass of the rod is taken

to be 2.00 kg.

Step 1

**Given:**

m_{1} = 4.00 kg

m_{2} =3.00 kg

Length of the rod, L = 1 m

Angular velocity of rod = 2.5 rad/s

Step 2

Calculating the moment of inertia of the system given that rod is of negligible mass:

Step 3

Calculating the kinetic en...
