Question

What is the velocity of a skater who is 10 kg, and has a Kinetic energy of 10000 Joules?

Answer 1

44.7 meter per second

Step-by-step explanation:

The formula to find velocity is

V = (2 · KE / m)^1/2

V = velocity

KE = Kinetic energy

m = mass

Let's calculate

(2 · 10000 / 10) ^1/2 = 44.7 meter per second
