Will give full points to whoever answers each question with a simple explanation! I really appreciate you taking time to help me!

The diagram below represents a strobe photograph of a ball as it rolls down the track. Choose two successive points. In the space at right, sketch the velocity vectors corresponding to those points. Draw the vectors side-by-side and label them v1 and v2 respectively. Determine the vector that must be added to the velocity at the earlier time to equal the velocity at the later time. Is the name change in velocity appropriate for this vector? How does the direction of the change in velocity vector compare to the direction of the velocity vectors in this case? Would your answer change if you were to select two different points during the rime that the ball was speeding up? Explain. In the space at right, draw a vector to represent the acceleration of the ball between the points chosen above. How is the direction of the change in velocity vector related Co the direction of the acceleration vector? Explain. Generalize your results thus far to answer the following question: What is the relationship between the direction of the acceleration and the direction of the. velocity for an object that is moving in a straight line and speeding up? Explain. Describe the direction of the acceleration of a ball that is rolling down a straight incline.
