Using calculus techniques to solve a construction problem
Purpose of this assignment:
Learners will be able to select and apply suitable mathematical techniques to solve practical construction problems.
Learning Aims: Learning Aim 2
Examine how calculus can be used to solve a construction problem.
Scenario:
You have been contracted as a mathematical consultant to solve and confirm a number of mathematical problems/solutions for projects on a major contract for the government, as explained below:
Task 1
The equation for a distance, s meters (m), travelled in time t seconds (s) by an elevator starting with an initial velocity u meters per second (ms-1) and uniform acceleration a meters per second per second (ms-2) is:
= +
If = − and = −:
a) create a suitable data table and hence draw a graph of distance s against time t for the first 5 seconds of motion.

b) using your graph, determine an approximate value for the velocity of the object when = 3.
c) use a numerical method to calculate an approximate value of the velocity when t = 3s.
d) use differentiation from first principles to find the function for the velocity v when time t=3s (Hint: =
).
e) compare and comment on the methods used and results obtained in parts b, c and part d.
If = − and = −:
f) find the velocity and the acceleration a of the object when t=2s and when
