Report

During a circus act, an elderly performer thrills the crowd by catching a cannon ball shot at him. The cannon ball has a mass of 10.0 $\mathrm{kg}$ and the horizontal component of its velocity is 8.00 $\mathrm{m} / \mathrm{s}$ when the $65.0-\mathrm{kg}$ performer catches it. If the performer is on nearly frictionless roller skates, what is his recoil velocity?

$v ^ { \prime } = 1.07 \mathrm { ms } ^ { - 1 }$

Okay, So consider that this with the direction of cannibal. And here is the former on suppose that they now combined. This is the kind of all now, as the popular catches the ball the combine together on moved at a certain velocity supposed to be considered. He says you initial moment. Um, the province A modem since the purple one. Street wasa crest. So here the total initial moment of most mass off ball times, velocity of a ball, right? The man didn't have any. The performer didn't have any moment. Um, the final moment, um, is both off ball and perform because they both slide on the rulers case. Right. So this should be massive ball. Bless myself the far from over times because the moment Emmys conduct now in this question, the muscle balm is given us so much. Some kisses on dhe must off the platform. Er is 65. Easy, Solari. The initial velocity of the ball waas eight meters per second. Right. So, karma, this expression you get that? He is according to massive ball times initial velocity of a ball off muscle ball, plus myself bubble. You have all these three companies required here. That gives you these cartoons. 1407 meters per second. All right, so this answers to give a question.
