4. (5 points) What is the direction of acceleration of the motion described by the motion diagram? Recall that direction of acceleration is same as the direction of change in velocity vector. Therefore, you must draw change in velocity vector to answer this question. Moving to the right .. 5. (5 points) A ball was moving initially rolling with velocity 5 m/s to the east. A short kick makes it move towards the north with 5 m/s. What is the direction of the average acceleration of a ball during the kick? Recall direction of acceleration is same as direction of change in velocity vector therefore you need to draw change in velocity vector to answer this question. Warning: acceleration is not zero.
