Answer:
The astronaut can throw the hammer in a direction away from the space station. While he is holding the hammer, the total momentum of the astronaut and hammer is 0 kg • m/s. According to the law of conservation of momentum, the total momentum after he throws the hammer must still be 0 kg • m/s. In order for momentum to be conserved, the astronaut will have to move in the opposite direction of the hammer, which will be toward the space station.
Explanation:
a/b. The ball has velocity vector at time
where is the ball's initial speed and .
c. At its highest point, the ball has 0 vertical speed. This occurs when
d. Recall that
so that at its highest point,
e. This is just twice the time it takes for the ball to reach its maximum height, .
f. The ball's horizontal position after time is
so that after the time found in part (f), the ball has traveled
