In the figure shown the acceleration of A is, `vec(a)_(A) = 15 hat (i) + 15 hat (j)` then the acceleration of B is (A remains in contact in B)

A

`6 hat(i)`

B

`- 15 hat (i)`

C

`- 10 hat (i)`

D

`- 5 hat (i)`

Text Solution

Verified by Experts

The correct Answer is:
D

From wedge constant
`(a_(A))_(bot)=(a_(B))_(bot)`
`a_(AX) cos 53^(@) -a_(AY) cos 37^(@) = a_(B) cos 53^(@)`
`a_(B) = -5 m//s rArr vec(a)_(B) = -5 hat(i)`
