Answer 2

Answer:

Given :       m1=1kg            m2=5kg         u1=10  ms−1               u2=0

Momentum of the system just before collision, Pi=m1u1+m2u2

Pi=1×10+5×0=10 kgms−1

Mass of the combined object, M=m1+m2=6kg

Let velocity of combined object be v

According to conservation of momentum, momentum of the system just after the collision, Pf=Pi

⟹Pf=10 kg m s−1

Mv=10

or, 6×v=10        

or, v=1.67 m/s
