Two balls of clay, with masses m1 = 0.49 kg and m2 = 0.47 kg, are thrown at each other and stick when they collide. mass 1 has a velocity v1 = 3.2i m/s and mass 2 has a velocity of v2 = 1.6j m/s. part (a) write an expression for the initial momentum of the system. p, in terms of the masses m1 and m2, the magnitudes of the velocities vi and v2, and the unit vectors i and j part (b) find the horizontal component of the final velocity vx, in meters per second, after the collision δ 33% part (c) find the vertical component of the final velocity vy, in meters per second, after the collision

This simply states that energy cannot be created or destroyed, it can only be transferred from one form to another. ... This dissipated heat energy cannot be regained in a useful form. Fuels. A fuel releases energy when it undergoes a chemical reaction.
