Q1. A plane accelerates from rest at a constant rate of 5 along a runway that is 1800 long. Assume that the plane reaches the required takeoff velocity at the end of the runway. What is the time needed to take off?

Q2. The cubit is an ancient unit. Its length equals six palms. (A palm varies from 2.50 to 3.50 inches depending on the individual.) We are told Noah's ark was 300 cubits long, 50 cubits wide and 30 cubits high. Estimate the volume of the ark (in cubic feet). Suppose the ark has a shoe-box shape and that 1 palm = 2.7 inch.
