Solve.In physics, if an object is in motion it has kinetic energy. The formula 
is used to calculate the kinetic energy, E, of an object with a mass m and velocity v. If the mass is measured in kilograms and the velocity is in meters per second, then the kinetic energy will be in units called joules (J). Suppose an object with a mass of 40 kilograms has 2,000 joules of kinetic energy. Find its velocity. Round to the nearest tenth if necessary.
