An object is shot vertically upward into the air with a positive initial velocity. what correctly describes the velocity and acceleration of the object at its maximum elevation?

Velocity is zero, Acceleration is negative

Explanation:

This situation describes the parabolic movement, when the object is shot vertically upwards its velocity is positive, while the acceleration due to gravity will always be negative (because its direction is in the direction of the center of the Earth); until the object reaches its maximum height where the speed is zero and then it begins to fall until it hits the ground.

Therefore, the answer is:

Velocity is zero, acceleration is negative

yup its correct its: c) b b
