for question 7
I got radius as 1.6 and length as 0.955 but everyone got different answers. /:

Speed was 1.6 for first part :S

 

[Sannikutti]

Can u tell me what 2ii) was...? I don't remember

What did u get for the 7i)?
Length and speed

 

[Sannikutti]

The length was 0.536 something for the last question.

Does the angular velocity changed for 7ii)?

I even forgot about this thing, but why is 0.5 wrong btw?

 

[Sannikutti]

cuz u should take the Diameter in the spehere question
U took radius
Cuz when the sphere is placed on table pivot is base of the sphere
But it can be 0.5 as well
Cuz if u take moment about O it force exerted by the surface is directly below O so it can be 0.5 as well
Lets hope for every thing
Btw how much u got for the speed of the mass i got 2.3 i think
any way take care and Enjoy ur holiday Bro
