Two blocks are moving towards each other on top of a smooth portion of a table, which is 3.56 m above the ground. Block 2 moves to the right at 8.55 m/s and has a mass of 9.47 kg. Block 1 moves to the left at 3.31 m/s and has a mass of 2.68 kg. The blocks collide, and block 2 moves to the right at 5.77 m/s after the collision. The collision takes place to the left of a rough patch of the table, which has a length of $L = 2.4 m$ and $\mu_{k1} = \mu_{k2} = 0.75$. Using only momentum/energy methods, determine the speed at which blocks 1 hits the ground, and how far away from the edge of the table (in cm) block 2 stops.
Ans. $v_{1floor} = 8.77 m/s$, block 2 stops 13.7 cm before the edge
