Question
A block A of mass m is placed over a plank B of mass 2m. Plank B is plank over a smooth horizontal surface. The coefficient of friction between A and B is 0.5. Block A is give a velocity v0 towards right . Acceleration of B relative to A is
Options
A.
B.g
C.
D.zero
Solution
Acceleration of B,
aB =
P & D of block A w.r.t. B
aAB =
= μg + aB = 
aB =
P & D of block A w.r.t. B
aAB =
= μg + aB = Create a free account to view solution
