![The distance y = 2.3 m. Find the upward velocity of A if the downward velocity of B is 2.7 m/s. Neglect the diameters of the pulleys.
8 m
A
B
Part 1
The motions of A and B are constrained because they are connected by a rope of constant length. The length of the rope
depends on the distances sĄ and y which change. Write an expression for the length Lof the rope in terms of the variable
distances SĄ and y and the fixed distance 8 m. If the distance SĄ = 2.3 m and y = 2.3 m, how long is the rope that connects moving
point A to fixed point C?
8 m
B
Answer: L = i
