A man sits on a chair supported by a rope passing over a frictionless fixed pulley. The man who weighs 1,000 N exerts a force of 450 N on the chair downwards while pulling the rope on the other side. If the chair weighs 250N, then the acceleration of the chair is

Answer»

`0.45m//s^(2)`
0
`2m//s^(2)`
`9//25m//s^(2)`

SOLUTION :For MAN: `T+F-W_(p)=m_(p)a`
For CHAIR : `T-F-W_(C)=m_(c)a`
