From the reference frame of the earth, two balls (one of mass m and the other of mass m) are moving horizontally towards one another. the small ball, m, is moving to the right (+i) with a speed of v, and the large ball is traveling to the left (-i) with a speed of u. the bals elastically collide and stay on the r axis after the collisions. a) calculate the speed and direction the balls travel off with after the collision; assum (1 - zu). momentum and kinetic energy would be great starting locations for this problem.) (hint b) get numerical values for the final speeds of the balls given: m- 3kg, m 1kg, 3, and5 c) use a galilean coordinate transformation to go into the large ball's point of view before the collision and get the velocity of the sa ball and large ball before and after the collision. you can just use your numerical results from part (b), the algebra gets rather hairy otherwise. remember your directions! d) using the numbers you got from part (c), check to see if the momentum and kinetic energy is conserved during the collision in the large ball's reference frame. will the equations you used for momentum and kinetic energy worlk for special relativistic collisions? explain in 1 or 2 sentences.
