Question

Two blocks X and Y of masses 3 kg and 5 kg are initially at rest. Now the two blocks start moving towards each other and block X is found to move towards right with a velocity of 0.05 m/s then the velocity of block Y at that instant is


A
0.01 m/s

B
0.02 m/s

C
0.03 m/s

D
0.04 m/s

Answer 1

Answer:

C

0.03m/s

According To law of conservation Of linear Momentum

Pi = pf

pi = 0 (system at rest)

pf = m1v1 + m2v2
