Ahelicopter (m = 3250 kg) is cruising at a speed of 56.9 m/s atan altitude of 185 m. what is the total mechanical energy of thehelicopter? a) 6.91 x 107 jb) 5.26 x 107 jc) 1.12x 108 jd) 2.27 x 108 je) 3.91 x 107 j

The mechanical energy of the helicopter is .

Explanation:

It is given that,

Mass of the helicopter, m = 3250 kg

Speed of the helicopter, v = 56.9 m/s

Position of the helicopter, h = 185 m

The energy possessed by an object due to its motion is called its kinetic energy. It is given by :

The energy possessed by an object due to its position is called its potential energy. It is given by :

The sum of kinetic and potential energy is called mechanical energy of the system. It is given by :

or

So, the mechanical energy of the helicopter is . Hence, this is the required solution.
