There r a few more. Please answer them asap....I'm so screwed for my major test :(


Q. A steel ball is suspended from the ceiling of an accelerating carriage by means of two cords A and B. Determine the acceleration- a of the carriage which will cause the tension in A to be twice that in B

Ans-g/3 X root3

I don't even know where to begin from in this one. I'm flunking this test or sure

In the figure shown, friction force between the bead and the thread is mg/4. Find the time in which the bead loses contact with the string after the system is released from rest.

Ans- t= root of (8l/7g)

I'm getting root (8l/3g) ???
