Question

a body of mass 2kg initial moving with a velocity of 10 M per second collides with another of mass 5kg at rest after collision velocity of 1st body becomes 1 metre per .
find the velocity of second body

Answer 1

Hello here is your answer

^_^

Given - M1= 2kg

U1= 10m/s

M2= 5kg

U2=0

After collision..

V1= 1m/s

V2=?

By the law of conservation of momentum..

m1u1+m2u2=m1v1+m2v2

Therefore..

2×10+ 5×0=2×1+5v2

20=2+ 5v2

So, 5v= 18

v= 18/5

=3.6m/s 2

Answer 2

I hope this is correct...
