1d collisions head on collisions sticking together ANSWER : mv - mv = collective mass x v 1d collisions in the same direction not sticking together ANSWER : mv + mv = mv + mv 1d collisions in the same direction sticking together ANSWER : mv + mv = collective mass x v 1d explosions ANSWER : mv + 0 = collective mass x v 1d recoil ANSWER : 0 = mv + mv Gun velocity will be negative as it is going back 2d collisions ANSWER : Total momentum in vertical component Total momentum in ho...

Question 1 Correct 6.00 points out of 6.00 The main pipe coming into a factory is 8 m in diameter, and the water in that pipe enters the building at 1 m / s. Once inside, however, the pipe divides into four pipes that are each4 m in diameter. Which of the following is the velocity of the water in the smaller pipes? Select one: a. 2 m / s b. 4 m / s c. 0.25 m / s d. The velocity in the smaller pipes is the same as the velocity in the larger pipe. Question 2 Correct 6...
