Calculate your Kinetic Energy in Joules if you weigh50 kg and you are walking 2 meters/second.

This is what I did:
KE is Ek=1/2mv^2
So it would be Ek=1/2(50kg) x 2m/s
Then I convert kg to pounds. There are .454kg in 1 lb so 50(.454)=22.7lbs
Ek=1/2(22.7lbs)(2m/s) = 22.7
Then what?

Great job so far! You correctly used the formula for kinetic energy, which is Ek = 1/2mv^2, where m represents mass in kilograms and v represents velocity in meters per second.

However, it looks like you made a small mistake when converting kilograms to pounds. The correct conversion is 2.2046 pounds in 1 kilogram. So let's correct that:

We have m = 50 kg and v = 2 m/s, so the formula becomes:
Ek = 1/2 * (50 kg) * (2 m/s)^2.

Now we can substitute the values and calculate:

Ek = 1/2 * (50 kg) * (2 m/s)^2
= 1/2 * (50 kg) * (4 m^2/s^2)
= 100 kg*m^2/s^2.

So, your kinetic energy is 100 Joules (J). Note that Joules are the units of energy.

It's important to use the correct conversion factors when performing unit conversions to ensure the accuracy of your calculations.
