Unformatted text preview: c. Determine x ( t ) of the united mass after the collision. Specify the amplitude and frequency of the motion. 2. We assume that there is no friction between m 1 and the horizontal surface, and that the collision between m 1 and m 2 is instantaneous and elastic. a. Find the two velocities u 1 and u 2 immediately after the collision (hint: do calculations in centerofmass coordinate system). b. Write the equation of motion for m 1 after the collision. c. Determine the trajectory x ( t ) of m 1 after the collision, and specify oscillation amplitude and frequency. 3. What is the SI unit of k ?
