Question

The system shown in the figure at the right consists of a light, inextensible cord, light frictionless pulleys and blocks of equal mass. Initially the blocks are at rest and at the same height above the ground. The blocks are then released. Find the speed of block A at the moment when the vertical separation of the blocks is h.
Note: inextensible means that it cannot be stretched.

Answer 1

Initial position of blocks

Answer 2

is their any measurements given?

Answer 3

mgh=1/2(mv^2)
v=sqrt(2gh)

Answer 4

bt the height is not given

Answer 5

vertical distance is given

Answer 6

wht is it?

Answer 7

wht is the vertical distance?

Answer 8

@Ell

Answer 9

Wouldn't you use the formula for acceleration?

Answer 10

yes, the problem is that it is complicated, because of the second block

Answer 11

A= V2 - V1/ t
1/2= 2/t
Solve for t
....sorry if this isnt right, this problem is kind of confusing me....

Answer 12

anyway, thx
