Write the actual function that you expect the velocity to obey as a function of time (recall that the initial velocity was 17 m/s). Your function should be a function of time (i.e. the t variable should be left as an independent variable) but all other values should be filled in with numbers. Based on your answer above, what type of curve would you expect the position vs. time function to obey? i.A constant (horizontal) curve? ii.A linear curve? iii.A quadratic (parabolic) curve? iv.Another type of curve, such as cubic, exponential, sine, square root, etc...? Circle an answer from above and explain how you use your answer to the above question and the relationship between position and velocity to arrive at your conclusion.
