A speedboat travels in a straight line and increases in speeduniformlyfrom vi = 16.5 m/sto vf = 39.5 m/s in adisplacement Δx of 165 m. We wish tofind the time interval required for the boat to move through thisdisplacement.
(a) Draw a coordinate system for this situation. (Submit a filewith a maximum size of 1 MB.)(b) What analysis model is most appropriate for describing thissituation?
particle under constant speedparticle under constantacceleration particle in equilibrium
(c) From the analysis model, what equation is most appropriate forfinding the acceleration of the speedboat?
vf = vi + at
Δx = vi + 1/2 at2
vf2 = vi2 +2aΔx
(d) Solve the equation selected in part (c) symbolically for theboat's acceleration in termsof vi, vf,and Δx.a =
(e) Substitute numerical values to obtain the accelerationnumerically. m/s2(f) Find the time interval mentioned above. s
