Two cars, X and Y, move along the same straight road for 20s starting from the same point at the same instant.
• Car X travels with a constant velocity of 15ms−1.
• Car Y starts from rest and moves with a uniform acceleration of 2ms−2 throughout the motion.
Answer the questions given below.
a. (i) Write the equation you will use to obtain the distance covered by car Y in the given time.
b. (ii) Calculate the distance travelled by each car in 20s.
c. (iii) Which car covers the greater distance in this interval? Explain with reference to your results.
