Question

a ball with a mass of 20 grams/moving at a velocity of 5 meters a second, what is the kinetic energy of the ball?

Answer 1

\[K=\frac{ 1 }{ 2 }mv^2\]

Answer 2

That's the formula for kinetic energy just plug in your numbers for the variables.

Answer 3

Velocity - 5m
Mass of ball is 20 grams, convert this into kg since we're using metric system, which is 0.02 kg, we get this by dividing 20/1000 because there's 1000 grams in a kg.
