FIGURE shows a cube of mass m sliding without friction at speed v 0. It undergoes a perfectly elastic collision with the bottom tip of a rod of length d and mass M = 2m. The rod is pivoted about a frictionless axle through its center, and initially it hangs straight down and is at rest. What is the cube’s velocity—both speed and direction—after the collision?
Solution 86 CP
Step 1 of 3
For a cube of mass ‘m’ sliding without a friction at speed , which undergoes elastic collision, with the bottom tip of a rod, we need to find , cube’s velocity, after collision.
