Answer 1

Answer:

Please find the answer below:

Step-by-step explanation:

Given:

m1 = 100 gram

= 100 × 1/1000

= 0.1 kg

u1 = 2 m/s

m2 = 200 gram

= 200 × 1/1000

= 0.2 kg

u2 = 1 m/s

From law of conservation of momentum:

m1u1 + m2u2 = m1v1 + m2v2

(0.1×2) + (0.2×1) = (0.1×1.67) + (0.2×v2)

0.2 + 0.2 = 0.167 + 0.2v2

0.4 - 0.167 = 0.2v2

0.233/0.2 = v2

1.165 m/s = v2
