5. Three kids are racing down a trail. I want to predict who will
win the race by calculating each kids kinetic energy. What
would I need to know about the kids to determine how much
kinetic energy each of them has? (hint - there are 2 pieces of
information I need for each kid)

Answer :

Half of an objects mass (1/2*m) multiplied by the velocity squared.

K.E. = 1/2*m*v2 ( v is squared, v*v )

To calculate someone’s Kinetic Energy you would need their mass, and the velocity in which they are moving. You would then need to get half of each persons mass, and multiply it by each of their own velocities squared. Hope this helps.v
