STIS: Physics Question:

Posted by Beaker (aka Anniebecca) Dec 16 '20, 16:44

A stationary bowling ball of unknown mass is hit head on by another hard ball of mass 2.5 kg moving to the right at 3.0 m/s. The 2.5 kg ball rebounds with a velocity of 2.0 m/s and the bowling ball moves to the right at 4.0 m/s.

What is the mass of the bowling ball?

(please give the equation as well please and thank you)

THANKS!

Is this the Kingpin conjecture or Lebowski hypothesis? -- nm - zeitgeist Dec 16, 19:25

I'm assuming this is in a frictionless vacuum? -- (link) - znufrii Dec 16, 16:53 1

- yup, it's a delta v - Reagen Dec 16, 16:56
- the 5 comes from adding the 3 to the rebound number of 2 right? Thanks so much! -- nm - Beaker Dec 16, 16:55
Are you trying to get someone else to do your kid's homework for you? You're just supposed screan and argue and not understand it until you all - JaxSean Dec 16, 16:50 3
- their Physics guy is a fucking dick. tests on stuff he hasn't covered. then covers it after the fucking test. -- nm - Beaker Dec 16, 16:55 2

- I'm sure there is an equation for this. I jusy no know Physics :) REAGAN ALERT! :) -- nm - Beaker Dec 16, 16:50
