Two motorcyclists standing at a junction. One runs right east and the other straight north. When the first one has traveled 150 meters, she has come up at a speed of 80 km / h. At the same time, the other has driven 200 meters and has the speed of 100 km / h. How quickly does the distance between riders increase at this time?

(All speeds are instantaneous speeds.)

Homework Answers

Answer #1

distance towards north

acceleration towards north

Similarly for east

diatadis covered in east

velocity in east

acceleration in east

As both riders start from rest and initial velocity in each direction are zero.

5. Two roads, one which runs north-south and the other which runs east-west intersect at Eagle Corners in Winslow Arizona. Bertrand is approaching Eagle Corners from the north at 60 km/h and Randy is leaving the Eagle Corners travelling west at 40 km/h. How fast is the distance between them changing at the instant Bertrand is 2.0 km north of Eagle Corners and Randy is 2.1 km west of Eagle Corners?

A girl is standing at a railroad crossing for a track that runs east and west. As she faces the track, east is to her right and west is to her left. Two trains on the track some distance apart are headed west, both at speeds of 7.20 m/s, and blowing their whistles (which have the same frequency). One train is approaching her from the east and the other is traveling away from her toward the west. (Assume the speed...

Two runners start one hundred meters apart and run toward each other. Each runs ten meters during the first second. During each second thereafter, each runner runs ninety percent of the distance he ran in the previous second. Thus, the velocity of each person changes from second to second. However, during any one second, the velocity remains constant. Make a position-time graph for one of the runners. From this graph, determine (a) how much time passes before the runners collide...
