You are looking at the mechanical processes which take place on the production line and need to use calculus to analyse what is taking place.

A particle moves along a horizontal line with displacement s given by,

s=5-te^(-t)

You may want to find expressions for the velocity and acceleration of the particle and potentially to find the maximum velocity of the particle.

You are looking at some of the flight statistics for one of the planes which have been manufactured, you find that when a plane takes off from an airport at sea level its altitude in feet at time t in minutes is given by: h=1800 ln( t+1 )

You may want to produce a graph to look at the altitude between 0 and 10 minutes and to use calculus to look at the rate of climb.

Just looking for a walk through, i have done a similar question and 3 of us have varying answers so got a little lost!
