Question

A submarine has a mass of 8,000,000 kg and is moving through the water at
a depth of 125 m with a speed of 6.2 m/s. What is its kinetic energy?​

Answer 1

Answer:

153760000 J

Explanation:

Kinetic energy is the energy possessed by a moving object solely due to its motion.

You can get the K.E. of an object using the equation,

K.E. =  (1/2)mv²

So you get, for submarine,

K.E. =  (1/2)×8000000×6.2²

      = 153760000 J = 0.153 GJ
