The bike's kinetic energy is 45 joules.
Basically, anything that moves.
Write the formula for kinetic energy. Replace the variables you know, with the corresponding numbers. Solve for mass.
As the object falls, it PEG or potential gravitational energy becomes kinetic energy. Before falling, it has for example 10 joules of PEG and 0 joules of Kinetic energy. As it falls, the PEG decreases and the kinetic energy increases, until it hits the ground, when all the energy is dispersed as sound, heat, etc.
Kinetic energy NORMALLY refers to bulk movement; for example, a vehicle might move over a road at a speed of 10 meters/second. That's the average speed of the vehicle; superimposed on that, the individual particles will still have their kinetic energy (which is technically also a type of kinetic energy).
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.

10-kj will be added to the Kinetic Energy. Remember the law of conservation of energy. E=PE+KE. and Efinal = Einitial.
