Using: r(t)=15+e*0.04tsin(pi*t/3)
"Explain why it takes longer to reach maximum heigh of the first ride but will exceed it."
Do i have to use this equation or the previous one of: s(t) = 15+6sin(Pi*t/3). to explain why?
Also, to find the distance off the ground as different time, in s, I replace the t in the bracket?
Many thanks!
use both equations.
e^.04t < 6 for t < 45
