Answer:

B. The vertical component of velocity is zero.

Explanation:

At the top of the flight, the gravitational acceleration g has stoped the vertical upwards motion of the ball momentarily before the vertical velocity starts to increase in the opposite direction.

Consider two less-than-desirable options.
Gemiola [76]

Answer:

The force would be the same in both cases - option C.

Explanation:

The change in momentum is known as an impulse. In the two cases under consideration, the change in momentum is the same, thus impulse for both cases is the same.

Impulse is the average force multiplied by time interval.

I = F(average)*ΔT. Where F(average) is the average force and ΔT is the time interval.

The average force in both cases is the same since the collision time is the same.

Thus option C is the correct answer.
