A speedboat increases its speed uniformly from v; = 20.0 m/s to v, = 30.0 m/s in a distance of 2.00 × 10² m. (a) Draw a coordinate system for this situation and label the relevant quantities, including vectors. (b) For the given information, what single equation is most appropriate for finding the acceleration? (c) Solve the equation selected in part (b) sym- bolically for the boat's acceleration in terms of v, V;, and Ax. (d) Substitute given values, obtaining that acceleration. (e) Find the time it takes the boat to travel the given distance.
