Question

A girl of mass 50kg jumps out of a going boat of mass 300kg on the bank ,with a horizontal velocity of 3m/s with what velocity will the boat move backwards
please answer it's urgent​

Answer 2

Answer:

0.5 M/S

Explanation:

m1=50 kg

m2=300 kg

v1= 3 m/s

v2=?

we have to find.

conservation of momentum=m1+v1+m2v2+0

0 is because no initial velocity is applied and the answer will be  

50 x 3 + 300v2=0

i.e v2 = -150/300=-0.5m/s

so it is moving backward direction the velocity (v2) will be 0.5m/s in the backward direction.
