It implies that Force opposes motion. Option C
First, we need to remember that;
a = dv/dt
Such that;
- a is acceleration
- dv is the change in velocity
- dt is the change in time
Then, we have that;
After point B, A would be negative since the value of dv/dt is negative.
Since, Force = mass ×acceleration
If a = negative, then force would also be negative, that is, force is experienced in opposite direction of motion.
