The drum in Figure 1.0 below has a mass moment of inertia of 28 kg.m² . A mass of 3 kg is attached to the cord which is wrapped around

the drum. Neglecting frictional resistance,determine the time taken for the mass to drop 2.5 m after being released from rest, and the tension in the chord. The radius of the winding drum is 0.6 m .Q7).
