Question

A boy of mass 60 kg running at 3 m/s jumps on to a trolley of mass 140 kg moving with velocity of 1.5 m/s in the same direction. With what velocity will the two moves together?

Mai itna bura bhi nhi dikhta jo mujhe is dp se compare kiya jaye (◠‿◕)​

Answer 1

Answer:

Both will move with the velocity 1.95 m/s

Explanation:

this is a kind of inelastic collision

So,

by applying conservation of momentum

60 X 3 + 140 X 1.5 = (60+140)v

180+210= 200v

390/200= v

1.95=v
