Answer:
-5 m/s²
Explanation:
Acceleration = change in velocity / change in time
a = (v − v₀) / (t − t₀)
a = (-0.4 m/s − 0.6 m/s) / 0.2 s
a = -5 m/s²
The ball decelerates at a rate of -5 m/s².
Answer:
9 m
Explanation:
i did the test and got 100%
Answer:
man will move in opposite direction with speed

Explanation:
As we know that man is lying on the friction-less surface
so here net force along the surface is zero
so if we take man + stone as a system then net change in momentum of this system will become zero
so here we have


here we have
