pls give the solution on paper step wise with reason...​

Answer 1

Answer:

Explanation:

We can solve it using differentiation with respect to x,as

a=v×dv/dx

=8×2

=16

,but in the given graph velocity is decreasing and becomes 0

So,we can say that the acceleration working on the body lowers the velocity i.e. deceleration is working on the body,

So the acceleration in taken in the negative y-direction ,as it is deceleration.
