As part of a department store display, a model train D runs on a slight incline between the store's up and down escalators. When the train and shoppers pass point A, the train appears to the shopper on the up escalator B to move downward at an angle of 22° with the horizontal, and to a shopper on the down escalator C to move upward at an angle of 23° with the horizontal to travel to the left. Knowing that the speed of the escalators is 3 ft/s, determine the speed (ft/s) of the train.

As part of a department store display, a model train D runs on a slight incline between the store's up
and down escalators. When the train and shoppers pass point A, the train appears to the shopper on the
up escalator B to move downward at an angle of 22° with the horizontal, and to a shopper on the down
escalator C to move upward at an angle of 23° with the horizontal to travel to the left. Knowing that the
speed of the escalators is 3 ft/s, determine the speed (ft/s) of the train.

Dr. L. and his cat Kepler are coming home from fishing. They ended their trip on the southbank of a 1200 m wide river, directly across from where Caroline is waiting to pick them upon the north bank. They are in identical boats that travel at 4 m/s (VB) on still water. Theriver is normally ‘lazy’ and flows with negligible velocity. On a calm day, if they pointed theboats north, they would cross the river in exactly 300s. However, today, the river is flowingdue east with a constant velocity (VW) of 1 m/s relative to the ground. Kepler, because shedoesn’t know better (she is a cat after all), has not taken this into account. Without payingattention, Kepler keeps the boat pointed due north for the entire trip. A) Relative to the ground, what is Kepler’s velocity? Derive an algebraic solution(in terms of VB and VW only) and then give a numerical answer (three significant figures isfine) expressed in degrees relative to due north (e.g. ‘42.3° west of north’).

A camera operator is filming a nature explorer in the Rocky Mountains. The explorer needs to swim across a river to his campsite. By watching debris flowing down the river, the operator estimates that the stream is flowing at 0.633 m/s. In still water, the explorer can swim at 0.759 m/s. At what angle, less than 90°, with respect to the shoreline should the operator advise him to swim so that he travels directly across the stream to his campfire? angle: 33.389 The water is near freezing in temperature. Typically a human can only swim in such water for about 300 s (or 5 min) before hypothermia sets in. Calculate the time the explorer spends in the water if the river is 28.3 m wide. time in the water: 81.03 S Incorrect Based on the results, what should the camera operator's decision be about the explorer's swim? Approved. He will get cold but he should be able to make it across. Sorry, but the swim must be cancelled. He will never make it across in time.
