PHYSICS HW HELP?
What is the kinetic energy of a 62kg cyclist if she is moving if she is moving on her bicycle at 8.2 m/s?

Ek = 1/2 m v^2 and you should note that v^2 is just v * v
so can you multiply 1/2 * 62 * 8.2 * 8.2 J? Really? Somehow I am dismayed at the question. Substituting numbers is easy and isn't physics. I may be judgmental if I feel that is the best way of helping you to be better. If you don't like my advice then you are in deep trouble.

KE = 1/2 * mass * speed^2
Substitute and solve, easy calc.

Kinetic Energy in J if m is in kg and V is in m/s
KE = ½mV²
KE = ½62•8.2² = ____ J
you have a calculator....
