Mechanical energy problem 4 part 3

The video tutorial covers a physics problem involving two blocks connected by a spring. The goal is to determine the velocity of block B after it falls a certain distance. The instructor reviews previous videos, derives equations using mechanical energy principles, and simplifies algebraic expressions. Trigonometry is used to calculate displacement, and the final velocity is determined. The video concludes with a discussion on the direction of the velocity and a brief mention of future topics.
