Answer to Question #157796 in Quantum Mechanics for lhyrio morada

Question

Alden works as an astronaut who has been sent to the International Space Station (ISS). At one instance while he is at rest, Alden throws a 5.0-kg bowling ball away from him at a rate of 2.0 m/s relative to ISS. At what speed and direction will he start to move after he releases the ball? *

Answer 1

According to the law of conservation of momentum

$Mv+mu=0\to u=-\frac{Mv}{m}$

If the mass of Aldene $76(kg)$, we get

$u=-\frac{Mv}{m}=-\frac{5\cdot 2}{76}=-0.13(m/s)$ opposite to the direction of movement of the ball. Answer
