Question

a ball of mass 100g and another ball of mass 200g move towards each other with speeds of 10 m/s and 2 m/s respectively. if they stick to each other after colliding, what would be the velocity of combined mass after the collision​

Answer 1

Answer:

4.6m/s

Explanation:

By formula m1u1+m2u2=m1v1+m2v2

mass of 1 ball=100g

mass of 2ball=200g

initial velocity of 1ball=10m/s

initial velocity of 2ball=2m/s

$100 \times 10 + 200 \times 2 = 100v + 200v \\ \\ 1400 = 300v \ \: \: \frac{1400}{300} = v \\ \\ v = 4.6$
