SUMMARY
The momentum of a 0.15 kg ball thrown straight up with an initial speed of 17 m/s at its maximum height is zero. At maximum height, the velocity of the ball is 0 m/s due to the effect of gravity, which decelerates the ball until it stops momentarily before falling back down. The formula for momentum, defined as momentum = mass x velocity, confirms that with a velocity of 0 m/s, the momentum is also 0 kg·m/s.
