Consider a classical inelastic collision of the form a + b -> c+ d. (for example, this could be a collision such as na + cl -» nat + cl in which two neutral atoms exchange an electron and become oppositely charged ions.) show that the law of conservation of classical momentum is invariant under the galilean transformation if and only if total mass is conserved- as is certainly true in classical mechanics. (we shall find in relativity that the classical definition of momentum has to be modified and that total mass is not conserved.)

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
