[size=150][b]A particle moves along a straight line and pasees through a fixed point [i]O. [/i]Its displacement, [i]s[/i] m, is given by [i]s=2t[sup]2[/sup]-5t-3, [/i]where[i] t [/i]is the time in seconds after the movement begins.[/b][br][br][b](a) Find the instantaneous displacement, in m, of the particle when [/b][b][br] (i) [/b][i]t [/i][b]= 0[/b][/size]
