Answer:
(a) Boojho is in zero acceleration
(b) No , it is a non-uniform acceleration
(c) 1.125 km/h
Explanation:
(a) The graph between point B and C indicates that boojho is in zero acceleration. Because boojho hasn't done any displacement between point B and C
(b) from 0 (zero) to point A the spped of boojho is constant.
From point A to B ,boojho has increased his speed, because he covered from more distance in less time as compared to point 0 (zero) to point A
(c) Total distance covered from point C to D = 225 - 150 = 75 m
Total time taken from point C to D = 12 - 8 = 4 m
4 * 60 = 240 s
Speed = Distance / Time
= 75 / 240
= 0.3125 m/s
= 1.125 km/h
