During july 1994 the comet shoemaker-levy 9 smashed into jupiter in a spectacular fashion. the comet actually consisted of 21 distinct pieces, the largest of which had a mass of approximately 4.0 · 1012 kg and a speed of 6.0 · 104 m/s. jupiter has a mass of 1.9 · 1027 kg and an orbital speed of 1.3 · 104 m/s. if this piece of the comet had hit jupiter head on, what would have been the change (magnitude only) in jupiter’s orbital speed (not its final speed)?

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
