Answer: 100 J

Explanation: 1/2 5 x 2^2 = 100

Hope this made any sense.

A 50-kg object should have 100J kinetic energy if it is moving at a velocity of 2 m/s.

Explanation: Just use the formula! Remember to:

Plug in the weight/mass to find m

Plug in the speed/velocity to find v

So the equation changes from    1/2 x M x V^2

to...

1/2 x 50 x 2^2

^

this is equal to 100.
