A school bus starts from rest and moves along a straight road with uniform acceleration. Answer the following questions based on this situation:
a. (a) Write the second equation of motion for uniformly accelerated motion in a straight line, clearly stating what each symbol represents.
b. (b) If the bus accelerates uniformly at 1.2m/s2 for 15s, calculate the distance it covers in this interval.
c. (c) For the same time interval, how far would the bus travel if the acceleration were 0.8m/s2? Compare the two results obtained in parts (b) and (c).
