Explanation Given information: At t = 0 , x = 0 , v = 54 k m / h For t = t 1 v = 54 k m / h Formula used: v = s t A = 1 2 b h Calculation: Firstly we will convert, 54 k m / h = 15 m / s . Now we have, v b = v a + ( a r e a u n d e r a − t c u r v e f r o m t a t o t b ) To determine (b) The position of the car at given time. To determine (c) The average velocity of the car during the interval at given condition.
