Three students, each having a mass of 60 kg, climb onto a large flatbed cart that has a mass of 120 kg. Standing at one end and taking turns they run to the opposite end and jump off, one immediately following the other, each with a velocity of 10 m/s with respect to the cart. Calculate the final velocity of the cart and students with resepect to the earth.(adsbygoogle = window.adsbygoogle || []).push({});

I know that we have to use:

m1*v1 + m2*v2 = m1*v1 + m2*v2

the left side is before and the right side is after

m1 = mass of object A

v1 = velocity of object A

m2 = mass of objectB

v2 = velocity of object B

Any help will be appreciated.
