A pulley with an unknown mass has a 0.3 m radius that is initially at rest. The rotational inertia of the pulley is 0.35 mr2. A 10 kg box hangs from a rope that is wrapped around the pulley that is also initially at rest. The box accelerates downward a distance of 10 m and reaches a velocity of 8 m/s. Calculate the mass of the pulley.

Units and Dimensions

These are generally defined as the terms which precede or describes the dimensions further. These are also further divided into two parts namely fundamental units and the derived units.
