Quandaries and Queries 

Question:
I assume that I need to integrate the equation to get the helicopter's position. Am I doing this correctly? If so, how can I get the final answer? Hi Kate, You are correct, integrate the expression for v(t) to get an expression for the position function s(t). When you do so you introduce a constant of integration C. To find C use the fact that the helicopter is on the ground at time t = 0 seconds, that is s(0) = 0. Write down this equation and solve for C. Once you know s(t) you can find s(3) which is the hieght of the helicopter after 3 seconds. Cheers,Penny
