Question

The kinetic energy of an object is described with the formula K = v2 where K is the kinetic energy of the object in joules (J). m is the mass of the object in

kilograms (kg), and v is the velocity of the object in meters per second (w). What is the velocity of an object with a kinetic energy of 375 J and a mass of 50
kg?

Answer 1

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of
