18. A4 kg bird is flying horizontally with a velocity of 4m/s at a height of 4 m. Calculate the total mechanical energy of the bird. Do 188.8 J 9.8J Do 156.8 J 39.2.

To calculate the total mechanical energy of the bird, we need to consider both its kinetic energy and potential energy.1. Kinetic Energy (KE):The kinetic energy of an object is given by the formula: where is the mass of the object and is its velocity.Given:Mass of the bird, Velocity of the bird, Substituting the values into the formula: 2. Potential Energy (PE):The potential energy of an object at a height is given by the formula: where is the acceleration due to gravity.Given:Height of the bird, Acceleration due to gravity, Substituting the values into the formula: 3. Total Mechanical Energy (TME):The total mechanical energy is the sum of the kinetic energy and potential energy: Therefore, the total mechanical energy of the bird is 188.8 J.
