Question

an object of mass 50 kg is moving with a velocity of 10 m/s and collide With another object of mass 100 kg moving with 20 m/s after collision velocity of 1 object change to 5 m/s find velocity of 2 object​

Answer 1

Answer:

Answer

Correct option is

A

3

2

m/s

Net momentum before collision is 2kg×3m/s+(−1kg×4m/s)=2Kgm/s, negative sign because in opposite direction.

After the collision the get stuck to each other so the mass becomes 1+2=3kg

if the new velocity is v then the new momentum should be equal to the old one, so 3v=2 or v=

3

2

m/s in the

direction of original direction of 2kg
