?? ok, first rl.bhat, cos90=0 90=16t+.7 89.3=16t 5.58=t (same answer i already got) ideasrule, i get the same answer when doing what you want me to do. I'll write out my derivation just for thoroughness. ________________d/dt[(27.1)(sin(16t+.7))] product...

Does 3.196 s sound like a better answer? I changed my calculator from degrees to radians. (if this fixes my problem, sorry for the stupid mistake) If not, rl.bhat, I do not understand what you want me to do. If I take the derivative at the maximum, where velocity is zero, it will also be zero.

Homework Statement The motion of an object is simple harmonic with equation of motion x = (27.1 m) sin(16.0 t /s + 0.7). At what time after t = 0 will the displacement reach its first maximum (where velocity equals zero)? Homework Equations (displacement)=Asin(freq.*t+phase) The...
