MECHANICS Problem No. 65

Module # MECH_P_065_Douglas_C_Giancoli Statement The position of a ball rolling in a straight line is given by x = 2.0 - 3.6 t 1.1 t2, where x is in meters and t in seconds. (a) Determine the position of the ball at t = 1.0 s, 2.0 s, and 3.0 s. (b) What is the average velocity over the interval t = 1.0 s to t = 3.0 s? (c) What is its instantaneous velocity at t = 2.0 s and at t = 3.0 s?
