Unformatted text preview: x 2 and x 3 (that is, when the particle is at x m = ( x 2 + x 3 ) / 2 = 36 cm). Therefore, x m = 9 . 75 + 1 . 5 t 3 m = ⇒ t m = 2 . 596 in seconds. Thus, the instantaneous speed at this time is v = 4 . 5(2 . 596) 2 = 30 . 3 cm/s. (f) The answer to part (a) is given by the slope of the straight line between t = 2 and t = 3 in this xvst plot. The answers to parts (b), (c), (d) and (e) correspond to the slopes of tangent lines (not shown but easily imagined) to the curve at the appropriate points. (cm) x (a) 20 40 60 2 3 t...
