Question

a body of mass 40 kg jump with horizontal velocity of 5 m/s man of cart is 3kg . what is the velocity

help​

Answer 1

Answer:

Given :  boody mass=40 kg           lvelocity of body=5 m/s        Mcart​=3 kg

Initial velocity of cart  ucart​=0

Let the final velocity of cart be  V.

Applying conservation of linear momentum :    Pi​=Pf​

Or    M bodyl​+Mcart​ucart​=(Mbodyl​+Mcart​)V

Or    40×5+3×0=(40+3)V

⟹ V=43200​ m/s
