Answer:
This will help you make me branlist have a nice day
Explanation:
the slope of x−t graph gives velocity
Slope is divided by tanθ
θ= angle from +ve horizontal axis
(time axis in our case)
double derivative of r−t graph will give
slope of slope acceleration
as 0=

0 to A all tangent have +ve slope so velocity +ve
going 0 to A the alope tangent is
decreases ⇒ velocity decreases
So acceleration is −ve
checking similarly
B is formed to be wrong (False)
as tangent between A and B are having −ve slope do −ve velocity
