The kinetic energy k of an object in joules is given by the formula k = } mv?, where m is the object's mass in kilograms and v is its velocity in meters per second. An object's velocity is 20 meters per second and its kinetic energy is 48,000 joules. If it speeds up
to 30 meters per second, then what is its new kinetic energy?
