Question

two objects of lokg and 8kg aremoving in a straight road with a
velocity of 20m/s and is respectively. If the second object 8kg moves with
25 mls After collision, calculate final
velocity of first object lokg.​

Answer 1

Final velocity will be 16m/s.

Answer 2

Answer:

According to law of conservation of momentum; momentum before collision is equal to momentum after collision.

Momentum before collision = m×v

Momentum after collision = m'×v'

According to law of conservation of momentum;

m×v = m'×v'

Now, u can solve this problem...
