(a) A flywheel absorbs 24 kJ of energy on increasing its speed of 210 rpm to 214 rpm . Determine its kinetic energy.
Explanation
The kinetic energy of the flywheel is determined using the formula: Kinetic Energy = (1/2) \* I \* (ω2 - ω1^2). The moment of inertia of the flywheel is assumed to be 1 kg m^2 for simplicity. The initial and final angular velocities are calculated using the given speeds. The kinetic energy is then calculated using the formula.
