Answer:
When speed reduces, acceleration decreases
Explanation:
From first equation of motion;
[tex]{ \tt{v = u + at}}[/tex]
When time is constant:
[tex]{ \tt{v = 0 + kt}} \\ { \tt{v = kt}} \\{ \tt{v \: \alpha \: \: a}}[/tex]
When speed is decreasing, velocity and acceleration are in opposite directions.
