Answer:

<h2>10,000 J</h2>

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

v is the velocity

From the question we have

k =  \frac{1}{2}  \times 50 \times  {20}^{2}  \\  = 25 \times 400 \\  = 10000

We have the final answer as

<h3>10,000 J</h3>

Hope this helps you

Your code returns a number of 99.123456789 +0.00455679 for your calculation. How should you report it in your lab write-up?
Aneli [31]

Answer: Your code returns a number of 99.123456789 +0.00455679

Ok, you must see where the error starts to affect your number.

In this case, is in the third decimal.

So you will write 99.123 +- 0.004 da da da.

But you must round your results. In the number you can see that after the 3 comes a 4, so the 3 stays as it is.

in the error, after the 4 comes a 5, so it rounds up.

So the final presentation will be 99.123 +- 0.005

you are discarding all the other decimals because the error "domains" them.
