▶2/56 The preliminary design for a rapid-transit sys-
tem calls for the train velocity to vary with time
as shown in the plot as the train runs the 3.2 km
between stations A and B. The slopes of the cubic
transition curves (which are of form a + bt + ct² + dt³)
are zero at the end points. Determine the total
run time t between the stations and the maximum
acceleration.

r The speed of a boat in still water is V. A river flows with a speed of v₁. The boat travels distance of 14 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the V and V₁. Hint: Velocity = displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "V" and "v": Do V" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. Equation 1 (downstream): Equation 2 (upstream): Solve for: V₁² vb Write an algebraic expression; do not use numerical values except…
You have exactly 4 minutes 26 seconds to get to your next class on time and that classroom is 216 m east of where you are right now. First you run to your dorm room at an average velocity of 5.42 m/s to the south to pick up your calculator and your dorm room is 332 m south of where you were initially. What average velocity (magnitude only) do you now need to run from your dorm room to your classroom to arrive exactly on time? a. 1.49 m/s b. 5.42 m/s c. 1.93 m/s d. 2.06 m/s
