given below. 2) A 0.50 kg cart moves on a straight horizontal track. The graph of velocity v versus time t for the cart is U (m/s) 1.0 0.8 0.6 0.4 0 8 +0-4 0.2 20 n Kint 10 20 25 1 (s) -6.4 + 1 12 - 9 = 0- 6 3 -1.0 -1- 08 -18 . 0.2 9 - 0 a. Indicate every time t for which the cart is at rest. when line is moing from *= 45 and *= 185 b. Indicate every time interval for which the speed (magnitude of velocity) of the cart is increasing. From 4s to 9is and from 117 s to LO s c. Determine the horizontal position x of the cart at t = 9.0 s if the cart is located at x. = 2.0 m at to = 0
