Heya,
Answer is ➡ FALSE.
Justification ➡
⏩ In the situation when acceleration is positive and velocity is negative at the instant time taken as origin
⏩ Then, for all the time before velocity becomes zero, there is slowing down of the particle.
⏩ Such a case happens when a particle is projected upwards.

Answer:
Explanation:
False , if the initial velocity of a body is negative then even in case of positive acceleration, the body speeds down. A body speeds up when the acceleration acts in the direction of motion.
