February, 2022 EKR2104 (OCHE) CONFIDENTIAL 4/10 QUESTION 3: (20 Marks) As a chemical engineer working under FlyPlus.A Car Manufacturing Sdn. Bhd., you are required to inspect the test drive performance of a new car FlyPlus Harimau in the Shaw federal highway. Table below summarizes the velocity (v) of this car at different times. Time, t(a) 1.5 3 4.5 6 7.5 Velocity, v (km/h) 87.16 112.38 96.19 10953 98.25 (a) By using Simpson's rule, calculate the distance (3) travelled by FlyPlus Harimau between t = 1.5 h and t = 4.5 h (5 Marks) (b) By using multiple-application trapezoidal rule, calculate the distance travelled by the FlyPlus Harimau between t= 1.5 h and t = 7.5 h. (5 Marks) (C) By using second order forward finite divided difference, estimate the acceleration (a) of the FlyPlus Harimau at 1.5 h. (5 Marks) (d) By using fourth order centered finite divided difference, estimate the acceleration (a) of the FlyPlus Harimau at 4.5 h. (5 Marks) END OF QUESTION PAPER hp
