Hi guys, i have a problem with this one question......
A particle moves in a straight line. At time, t seconds, its displacement Xcm from a fixed point O in the line is given by
X= 5sin((Pi/2)t
Find the speed when x=2.5
Help would be greatly appreciated![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
