Answer 1

101,400 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

v is the velocity

From the question

m = 75 kg

v = 52 m/s

We have

`k = (1)/(2) * 75 * {52}^(2) \\ = (1)/(2) * 75 * 2704 \\ = 75 * 1352 \\ = 101400`

We have the final answer as

101,400 J

Hope this helps you
