Question

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?

Answer 1

Velocity Zero Acceleration Negative

Step-by-step explanation:

Because it is going vertically upwards so there is no velocity at the maximum and the acceleration turns negative as it falls down

Answer 2

Answer: Velocity is zero, Acceleration is negative

Step-by-step 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
