Question 4 - Motion of a Marble / 10 marks The position function of a marble moving along a track is s(t) = =(5 - -1_2) t for t = 10 a) Find the marble's velocity and acceleration function. b) When does the marble return to its starting position, s(0)? c) At what time(s) is the marble at rest? d) During what intervals are s(t), v(t), and a(t) positive and when are they negative? Summarize it in a chart (similar to what is shown in the next question). Question 5 - Sketch a Graph / 10 marks a) Sketch (plot) the graphs of position, velocity, and acceleration of a particle (for 0
