The correct answer is (A) 2.0 J
Total energy of the pendulum is the sum of its kinetic and potential energy. At the instant of time, when the pendulum is at a height <em>h</em> and has a speed <em>v, </em>Its energy is given by,
Substitute 2.0 kg for <em>m</em>, the mass of the pendulum, 9.81 m/s² for <em>g</em>, the acceleration due to gravity, 0.10 m for <em>h and 4.0 m/s for </em>v<em>.</em>
The pendulum has an initial energy of 20 J. the energy lost is given by,
Thus, the energy lost by the pendulum is (A) 2.0 J
- Velocity=108km/h
Convert to m/s
- Time=30s.
