how is this calculated plz explain

This is the application of second law of motion so the rate of change of momentum gives force so
dp/dt is equal to force
dp/dt is nothing but the slope at 3 sec
So slope is tan theta
That is 1/1 that is 1
So the negative sign must beacuse tge force is reducing the momentum to zero
Graphically -ve because we measure angle in anti-clockwise direction
