Solve the following question:
Question: A 10 kg block has a speed of 9 m/s as it begins to slide up a ramp inclined 20o above the horizontal. The static coefficient of friction is 0.4 and the kinetic coefficient of friction is 0.3. After the block travels 4 m, it collides with and STICKS to a stationary 5 kg block.
Question 1: What is the velocity of the blocks after the collision?
Show each step in detail to solve the above question.
