Q5.6
Blocks A and C are connected by a string as
shown. When released, block A accelerates to the
right and block C accelerates downward.
Although there is friction between blocks A and
B, there is not enough to prevent block B from
slipping. If you stood next to the table during
the time that block B is slipping on top of block
A, you would see
1. block B accelerating to the right 2. block B
accelerating to the left 3. block B moving at
constant speed to the right 4. block B moving at
constant speed to the left 5. none of the above
