questions. a) Draw a complete v – t graph. Label the axes with the appropriate variable and units. Provide an appropriate scale for each axis and clearly show the velocity at t = 0, t = 20 s, t =25 s, respectively. (3 points) b) What is the equation of velocity as a function of time, v =f (t), for the time interval of 0 < t < 20 s? Be sure to include appropriate units. (2 points) c) What is the equation of velocity as a function of time, v = ƒ (t), for the time interval of 20 s
