Where is the rest of the question/answers????
Lets solve for t in the height equation:
h = 7 cos (pi/3 t)
cos (pi/3 t) = h/7
pi/3 t = cos^-1 (h/7)
t = (3/pi) <span>cos^-1 (h/7)
then we substitute:
</span>t = (3/pi) <span>cos^-1 (1/7)
</span>t = 78.1 s
t = (3/pi) <span>cos^-1 (3/7)
</span>t= 61.71
t = (3/pi) <span>cos^-1 (5/7)
</span>t = 42.41
those are the times in seconds respectively.
