In the arrangement shown in the figure, the block C begins to move down at a constant speed of 7.5 cm//s at time t = 0. At the same instant blockA is made to start moving down at constant acceleration. It starts at M and its speed is 30 cm//swhen it reaches N (MN = 20 cm). Assuming that B started from rest, find its position, velocity and acceleration when block A reaches N.

1.	In the arrangement shown in the figure, the block C begins to move down at a constant speed of 7.5 cm//s at time t = 0. At the same instant blockA is made to start moving down at constant acceleration. It starts at M and its speed is 30 cm//swhen it reaches N (MN = 20 cm). Assuming that B started from rest, find its position, velocity and acceleration when block A reaches N.
Answer» ANSWER :Position; 40 CM up from starting position `V_(B) = 45 cm//s (uarr)` `a_(B) = 22/5 cm//s^(2) (uarr)`
