20 15 E 10 4 time ($) tim: (5) G. Two objects appear at the same place (15 cm) at 1 second, one disappears at 20 cm at 2 seconds while another appears at x = 0, both disappear at same location at 3 seconds. (Cannot reproduce with motion sensor. Not a function.) H. Constant velocity of +2 cm/s, acceleration = zero, change in position = 10 cm. I. Constant acceleration +0.8 cm/s, initial velocity = 0 cm/s. 3 tine (5) time (s) tine (5) 2 5. tina (s) Constant acceleration = -1 cm/s, initial velocity = +3 cm/s. tiae (5) J. K. Initial velocity = zero, acceleration is positive and increasing to about +1 cm/s/s. L. Initial velocity = zero. For first 2 seconds, acceleration =-2 cm/s, from 2-3 seconds, acceleration = +4 cm/s; after t = 3 seconds, both velocity and acceleration are zero. %3D M. Acceleration is initially negative, changes to zero. Initial velocity = 4 cm/s, decreases to about -1.5 cm/s. N. Initial velocity = 4 cm/s. Acceleration is initially negative, changes to zero by 3 seconds and remains zero. Final constant velocity = +1.5 cm/s. 0. Initial velocity = -2 cm/s, is constant for first 2 seconds.
