Bolt starts the race not moving, but then increased his speed until he reaches a top speed. Once Bolt reaches his top speed he maintains that speed for a few seconds to: a) move at constant velocity b) accelerate by moving faster c) accelerate by moving slower

a

Explanation:

In order to maintain speed, a moving object or person must move at a constant velocity. Accelerating will increase the speed while decelerating will reduce the speed.

Hence, for Bolt to be able to maintain the top speed for a few seconds, he needs to move at a constant velocity.

The correct option is a.

i don't know, you need to give me some answers.
