A pontoon boat travels across a lake in a straight line and increases in speed uniformly from vi = 18.5 m/s to vf = 36.0 m/s in a displacement Δx of 250 m. We wish to find the time interval required for the boat to move through this displacement. g
(a) Draw a coordinate system for this situation.
(b) What
analysis model is most appropriate for describing this situation?
(c) From the analysis model, what equation is most
appropriate for finding the acceleration of the speedboat?
(d) Solve the equation selected in part (c) symbolically for
the boat’s acceleration in terms of vi , vf , and ?x. (e) Substitute
numerical values to obtain the acceleration numerically.
(f) Find the time interval mentioned above.
