Two balls held together by a piece of plastic explosive move together with velocity having x-component-3.67. Ball #1 has mass 2.21 , ball #2 has mass 1.36, and the mass of the plastic explosive is negligible. Assume this is an isolated system. Later, the explosive explodes and the two balls fly apart and ball #1 is moving with velocity having x-component -7.34. What is the x-component of the velocity of ball #2? All quantities are given in SI units and the answer should be given as a positive or negative number in Sl units. Only type a number into the answer box, do not type in units.
