Question

A girl of mass 40 kg jumps into a horizontal velocity of 5 ms–¹onto a stationary cart with frictionless wheels. The mass of the cart is 3kg . What is the velocity as the cart starts moving
Assume that there is no external unbalanced force working in the horizontal direction​

Answer 1

Answer:

given :Mgirl=40 kg

Ugirl=5m/s

Mcart= 3kg

initial velocity of the cart Ucart=0

let the final velocity of the cart beV

Applying Conservation of Linear Momentum :Pi=Pf

orMgirl Ugirl+Mcart Ucart =(Mgirl+Mcart)v

=40*5+3*0=(40+3)v

v=200/43m/s
