Unformatted text preview: Lets start with Cons of linear momentum What other equation? Two equations, two unknowns Definitely an impact problem what are the different principles you would apply? Given: Find: v 1 = 0.8 ft/s, v 2 = 2.4 ft/s, e= 0.50, W 1 = 1.5 lbs and W 2 = 2 lbs v 1 and v 2 after impact, percent energy loss Problem type: Put in values Before the impact After the impact Calculate percentage energy loss =2.4 ft/sec...
