Confirm that the results of the example Example 8.7 to conserve momentum in bo?th the ?x? - a? -directions. Example 8.7 Determining the Final Velocity of an Unseen Object from the Scattering of Another Object Suppose the following experiment is performed. A 0.250- ? kg object (?m1) is slid on a frictionless surface into a dark room, where it strikes an initially stationary object with mass? of 0.400 kg (?m2) . The 0.250-kg object emerges from the room at an angle of 45.0° with its incoming direction. The speed of the 0.250-kg object is originally 2.00 m/s and is 1.50 m/s after the collision. Calculate the magnitude and directio?n of the? velocity ? ?2 and ??2) of the 0.400-kg object after the collision.
Step-by-step solution In this problem we have to calculate the Calculate the magnitude and direction of the velocity of object after collision as per the given condition respectively: Step 1 of 4 Suppose the following experiment is performed. An object with mass m1 is slid on a frictionless surface into a dark room, where it strikes an initially stationary object with mass m 2. Confirm that the results of the phenomena to conserve momentum in both the x –d irection and y –directions. Step 2 of 4 Along x -axis, momentum before collision is: Here, are the mass and velocity of the object with friction less surface respectively, are the mass and velocity of the stationary object respectively. Substitute for , for , for and for :
