[A] In all the questions I'll take g=10
Weight is same in both situations.
[B]
S1
which means the block is moving down.
S2
I'll assume downward this time.
[C]
We already calculated the net downwards acceleration
S1
Use the following, for initial velocity 0,
S2
Similarly, here
[D]
For velocity
S1
S2
