A person riding a bike has a mass of 55kg. They are moving with a velocity of 2m/s. What is the Kinetic Energy of the person?

Respuesta :

KE = 1/2mass • velocity^2
So, if we take half of 55, we get 27.5
Next, we take 2, and square it, getting 4.
Lastly, take 27.5, and multiply it by 4, getting 110 Joules, hope this helps and have a great day!

Explanation:

Formula : ½ × mv² (mass×velocity)

½ × 55 × 2²= ½×55×4=110J

(½ is also equivalent to 0.5)

J = Joules
