An object moves in one dimensional motion with constant acceleration a = 5.9 m/s2. At time t = 0 s, the object is at x0 = 4.1 m and has an initial velocity of v0 = 4.4 m/s. How far will the object move before it achieves a velocity of v = 8.5 m/s? Your answer should be accurate to the nearest 0.1 m.

7. For each of the motions below sketch a motion diagram as described in section You may use a dot to represent the object in motion. First, establish a coordinate axis for each motion. Draw arrows to scale above each dot to represent the velocity vector. Indicate the acceleration direction for each constant acceleration segment of the motion.
