[-/4 Points] DETAILS SERPSET9 2.P.037. A speedboat travels in a straight line and increases in speed uniformly from v; = 18.0 m/s to vy = 31.5 m/s in a displacement Ax of 190 m. We wish to find the time interval required for the boat to move through this displacement. (a) Draw a coordinate system for this situation. (Submit a file with a maximum size of 1 MB.)

(b) What analysis model is most appropriate for describing this situation? particle under constant speed particle under constant acceleration particle in equilibrium (c) From the analysis model, what equation is most appropriate for finding the acceleration of the speedboat? Ovr = vi + at O AX = Vi + +at2 Ov? = v12 + 204x (d) Solve the equation selected in part (c) symbolically for the boat's acceleration in terms of Vi, Vf, and Ax. a (e) Substitute numerical values to obtain the acceleration numerically. m/s2 (f) Find the time interval mentioned above
