Question
Block B has a down ward velocity in m/s and given by vB = 
, where t in s. Acceleration of A at t = 2 second is
, where t in s. Acceleration of A at t = 2 second is Options
A.2 m/s2
B.4 m/s2
C.6 m/s2
D.None of these
Solution
(4T ) aA = (2T) (aB)
⇒ aA =
but aB =
= t +
⇒ aA = 
At t = 2s,
aA =
1 + 1 = 2 ms-2Create a free account to view solution
