Question

The masses of two bodies are in ratio 4:3 and their velocities are in ratio 1.2 linear momentum will be in the ratio​

Answer 1

1:4

»KE2KE1=p22/2m2p12/2m1

Given » p1= p2= p(say)

»14=p2/2m2p2/2m1

»m2m1 = 41

Answer 2

Answer:

mass of 1st body=4, velocity=1m/s

we know that..,

p=mv       (where, p=linear momentum)

=4*1

 =4kg m/s

mass of 2nd body = 3, velocity = 2

therefore, p= 3*2

p = 6 kg m/s

therefore, the ratio will be 4:6

                                            =2:3
