Question

1) Two blocks A and B are connected by a massless string (shown in figure) A force of 30 N is applied on block B. The distance travelled by centre of mass in 2s starting from rest is
(1) Im
(2) 2m
(3) 3m
(4) none of these

​

Answer 1

Answer:

Pls give mass of A and B

Explanation:

Answer 2

Answer:

Explanation:F=Ma

30=30*a

a=1m/s

Now find distance,

S=ut+½at²

S=0×t+½×1×2×2

S=2m
