A small (35 g) block is sliding toward the right along a table when it hits a larger (90 grams) block that was at rest. After the collision, the large block slides 72 cm to the right before coming to a rest, while the small block bounces off the large block, sliding 1.5 m to the left before stopping. The somewhat rough table has a coefficient of kinetic friction of 0.42. What is the velocity of the small block just before it hit
