A 50-kg trainee for spaceflight ejects 100 g of gas from his propulsion pistol at a velocity of 50 m/s. what is his resulting velocity?

Sagot :

Indrawboyid

Momentum

m₁v₁=m₂v₂

50 x v₁=0.1 x 50

v₁=0.1 m/s

actually the direction of the gas to the right, the direction of the trainer to the left (pushed)
