Velocity is given by distance traveled per unit time. In the case of waves show that this leads to the velocity of the wave being equal to the product of the wavelength and the frequency.
A 20 g bullet moving at 1000 m/s is fired through a one-kg block of wood emerging at a speed of 200 m/s. What is the change in the kinetic energy of the bullet-block system as a result of the collision assuming the block is free to move?
