Question
Block A of mass m is placed over a wedge B of same mass m . Assuming all surface to be smooth . The displacement of block A in 1 s if the system is released from rest is
Options
A.
B.
C.
D.
Solution
Acceleration of B : a1 = 
Acceleration of A, a2 =
but
a1 sin θ = a2
⇒
⇒N2 = 
a2 = g -
Displacement =
a2t2 = 
Acceleration of A, a2 =
but
a1 sin θ = a2⇒
⇒N2 = a2 = g -
Displacement =
