In the adjoining figure velocities and acceleration of the blocks 1 and 3 at any instant are `v_(1) = 6 m//s` upwards `, a_(1) = 6 m//s^(2)` ( downwards ) and `v_(3) = 3m//s` ( upwards) `,a_(3) = 4 m/s^(2)` ( downward) respectively. Find the velocity and the acceleration of the block 2 at that instant.

Answer

`-15 m//s` ( downward ) , `16m//s^(2)` ( upward )
