Question

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

Answer 1

Answer:

5000 J

Explanation:

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

$k = \frac{1}{2} m {v}^{2}$

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

$k = \frac{1}{2} \times 100 \times {10}^{2} \\ = 50 \times 100 \\ = 5000 \: \: \: \: \: \: \: \:$

We have the final answer as

5000 J

Hope this helps you
