Question

answer the above question i will mark them as brainlist​

Answer 1

Answer:

Explanation:

Mass of 1st wagon=1/2 t=1/2 x 1000 kg=500 kg

Velocity of this wagon=10 km/h=2.8 m/s

Mass of 2nd wagon=3/2 t=1500 kg

It's velocity=15 km/h=4.17 m/s

According to the law of conservation of momentum,

Total momentum before collision = Total momentum after collision

(500 x 2.8) + (1500 x 4.17)=(500+1500) x v

1400+ 6255=2000 v

v=3.8 m/s

Thus, the final velocity of wagons is 3.8 m/s.
