The kinetic energy E of an object (in joules) varies jointly with the object's mass m (in
kilograms) and the square of the object's velocity v (in meters per second). An object
with a mass of 8.6 kilograms and a velocity of 5 meters per second has a kinetic
energy of 752.5 joules.
Write an equation that relates E, m, and v.
Then use the equation to find the kinetic energy of an object with a mass of 2
kilograms and a velocity of 9 meters per second.
