A 66-kg man stands on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.2 m/s in 0.90 s. The elevator travels with this constant speed for 5.0 s, undergoes a uniform negative acceleration for 1.

Describe the relationship between the direction of the velocity vector and the direction of the acceleration for a body moving in a circle at constant speed.
