Answer #1

6)(a) A train starting from a station.

The train has just started from rest from a station. it accelerates and its speed increases.

(b)A train on which brakes has been applied as it arrives it destination. So the acceleration is negative and speed decreases.

(c)A toy following a circular path, with direction changing every second and speed increasing but velocity decreasing and hence the accleration decreasing.

(d)Again a toy moving with displacement incresing so velocity will be increasing but speed is decrreasing, as velocity = displacement/time ; speed = distance/time.
