Explanation Given: It is known that x = − 540 m at t = 0 . a t is equal to the slope of v − t curve at time t . From t = 0 to t = 10 s : v = constant ⇒ a = 0 t = 10 s to t = 26 s : a = − 20 − 60 26 − 10 = − 5 m / s 2 t = 26 s to t = 41 s : v = constant ⇒ a = 0 t = 41 s to t = 46 s : a = − 5 ( − 20 ) 46 − 41 = 3 m / s 2 t = 46 s : v = constant ⇒ a = 0 To determine (b) Maximum value of position coordinates of the particle. To determine (c) Values of t for which particle is at x = 100 m .
