An object moves in a circular path at a constant speed. what is the relationship between the directions of the object's velocity and acceleration vectors? (a)-the velocity and acceleration vectors point in opposite directions. (b)-the velocity and acceleration vectors are perpendicular. (c)-the velocity vector points in a direction tangent to the circular path. the acceleration is zero.
(d)-the velocity vector points toward the center of the circular path. the acceleration is zero. (e)-the velocity and acceleration vectors point in the same direction.
