Is the acceleration positive or negative?What is the sign of acceleration that reduces the magnitude of a positive velocity?Synlain thonbucical chomical and biological factors which lead to the formation of coil15

Answer»

as we know ,v=u+at

since initial speed was u in negative direction ,and final speed is zerogives 0=u+atand a=-u/t.

1)shows that acceleration will act in positive direction2)if velocity is positive so to reduce it's magnitude acceleration should be in negative direction.
