A ball with a mass of 1.3 kg rolls off a table 0.35 m above the floor. Assuming a complete transformation of gravitational potential energy into kinetic energy, calculate the velocity of the ball immediately before it hits the floor.

Research the neutrino using the internet and report your findings. in a nuclear decay, the nucleus of an atom splits apart. larger particles can be detected and their masses and velocities can be recorded. explain how the existence and properties of the neutrino could be predicted using the conservation laws.
