Question

This is a velocity-time graph when
the body is under: *
​

Answer 1

Under what ?????????????

Answer 2

Explanation:

we know that a=

dt

dv

Clearly at and after point B, a will be negative since

dt

dv

is negative.

Now we know that F=ma

Since a will be negative, therefore F will also be negative i.e. force is experienced in opposite direction of motion.
