Question
The distance y - 1.6 m. Find the upward velocity of A if the downward velocity of B is 2.4 m/s. Neglect the diameters of the pulleys.
6 m
A
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 sa and y which change. Write an expression for the length Lof the rope in terms of the variable distances sa and y
and the fixed distance 6 m. If the distance sa - 1.6 mand y - 1.6 m, how long is the rope that connects moving point A to fixed point
6 m
B
Answer: L-
