Question

vhat can you say about the final velocity of an object if its acceleration is negative?​

Answer 1

Hi there,

_____________________________

caution'..... u cannot say the final velocity of the body will be zero.....

now, u need to understand..... for any type of motion ( with uniform acceleration) a Cartesian coordinated system is taken into account to track the motion parameters of the body in terms of vectors.....

so.... a negative as well as a positive direction exists....

and just because the body is moving a negative 2m on the x- axis dosent mean its travelling back in time n' all....

merely just the position of the body is traced...

similarly acceleration...

so.... as the body is retarded(-ve acceleration=> opposite to the motion of the body) ... the body's velocity reduces till it stops and the velocity starts increasing again in the direction of the initial accelearation....

so final velocity can never be zero... but keeps on increasing..
