Question

What is the kinetic energy of a 100kg ship moving along the water at a rate of 10m/s?

Answer 1

5000 J

Step-by-step explanation:

The kinetic energy of an object can be found by using the formula

`k = (1)/(2) m {v}^(2) \\`

m is the mass in kg

v is the velocity of the object in m/s

From the question

m = 100 kg

v = 10 m/s

We have

`k = (1)/(2) * 100 * {10}^(2) \\ = 50 * 100 \\ = 5000 \: \: \: \: \: \: \: \:`

We have the final answer as

5000 J
