Final Answer:
The diver's momentum at the highest point in the dive is 0 kg·m/s.
Step-by-step explanation:
At the highest point in the dive, the diver's velocity is 0 m/s. This is because the diver has reached the maximum height of their jump and is momentarily stationary before beginning to fall back down to the pool. Since momentum is the product of mass and velocity, a velocity of 0 m/s results in a momentum of 0 kg·m/s.
In conclusion, the diver's momentum at the highest point in the dive is 0 kg·m/s. This is because the diver's velocity is 0 m/s at that point.
