Final answer:
Yes, an object can have a northward velocity and a southward acceleration simultaneously.
Step-by-step explanation:
In physics, an object can have a northward velocity and a southward acceleration.
Velocity refers to the speed and direction of an object's motion. It is a vector quantity, meaning it has both magnitude and direction. Acceleration, on the other hand, refers to the rate at which an object's velocity changes. It is also a vector quantity. If an object is moving northward with a velocity of 10 m/s and it experiences a southward acceleration of 2 m/s^2, the object's velocity is changing in the opposite direction of its initial motion. This is an example of an object having a northward velocity and a southward acceleration simultaneously.
