Question

A 0.1 kg block suspended from a massless
string is moved first vertically up with an
acceleration of 5 ms - and then moved
vertically down with an acceleration of
5 ms. IfT, and T, are the respective tensions
in the two cases, then​

Answer 1

sorryyyyyyyy I don't know the answer

Answer 2

Explanation:

If the block is moving up

T-1=1.5

T=2.5

Therefore 2.5N is require to move the block vertically upwards,

Then if the block move downwards,

1-T=1.5

T=0.5N

Therefore 0.5N is require to move the block down
