Q. A tank of water 3.00m deep sits on a table 1.00 m tall. A hole is located 2.0m from the bottom of the tank. Water flows out of hole and strikes the ground. Where does it strike the ground?

Q. An unstable nucleus with a mass of 19.0 x10-27 kg initially at rest disintegrates into three particles. One of the particles, of mass 4.1 x10-27 kg, moves along the positive y-axis with a speed of 9.0 x10^6 m/s. Another particle, of mass 7.5 x10-27 kg, moves along the positive x-axis with a speed of 1.0 x10^6 m/s. (Assume that mass is conserved.)

Find out the third particle's speed.
