Answer:
A
Athey travel with a velocity of 5ms−1 in the same direction
Athey travel with a velocity of 5ms−1 in the same directionUsing momentum conservation for inelastic collision,
Athey travel with a velocity of 5ms−1 in the same directionUsing momentum conservation for inelastic collision,m1u1+m2u2=(m1+m2)v
Athey travel with a velocity of 5ms−1 in the same directionUsing momentum conservation for inelastic collision,m1u1+m2u2=(m1+m2)v10=4v⇒v=5m/s
