An athlete runs two-thirds of the way around a circular track of radius 50m. Determine her displacement relative to her starting point.

A runner, jogging along a straight-line path, starts at a position 60.0 m east of a milestone marker and heads west. After a short time interval he is 15.7 m west of the mile marker. Choose east to be the positive x-direction. What is the runner’s displacement from his starting point? Enter a positive value if the displacement is toward east of the milestone and a negative value if the displacement is toward west of the milestone.

A whale swims due east for a distance of 6.95 km, turns around and goes due west for 1.87 km, and finally turns around again and heads 6.37 km due east. (a) What is the total distance traveled by the whale? (b) What is the magnitude of the displacement of the whale? (a) Number Units (b) Number Units

A group of hikers sets out going 10.0km [N], then 15.0km [E], then 4.0km [S]. The entire trip takes 4.00h. Determine the magnitude hikers' velocity for the trip.    4.04 km/h [N 21.8° E]       5.25 km/h [N 21.8° E]       7.25 km/h [N 21.8° E]       21.0 km/h [N 21.8° E]       65.25 km/h [N 21.8° E]

1. A pilot in a small plane encounters shifting winds. He flies 26.0 kmkm northeast, then 45.0 kmkm due north. From this point, he flies an additional distance in an unknown direction, only to find himself at a small airstrip that his map shows to be 70.0 kmkm directly north of his starting point. What was the length of the third leg of his trip?   What was the direction of the third leg of his trip?   2. A boat can travel   7.3  m/s in still water.  It is crossing a   220   m wide river while pointed due east and the river is flowing at   3.7   m/s, north.   What is the speed of the boat, relative to the shore? How long does it take to cross the river? How far downstream does the boat end up?   3. A flock of ducks is trying to migrate south for the winter, but they keep being blown off course by a wind blowing from the west at 14 m/sm/s . A wise elder duck finally realizes that the solution is to fly at an angle to the wind.   If the ducks can fly at 15 m/sm/s relative to the…

A person walks north 5m, west 10m, and south 5m. What is their displacement? a. Om b. 10m west с. 5m d. 5m south

Ann walks 135 m north from point A to point B. She then turns around from point B and travels south 15 m. What is her final displacement from point A?   (a) 150 m north   (b) 150 m south   (c) 120 north   (d) 120 south   (e) 120 m

1) A race car travels around a circular race track for which the start line and finish line are at the same location.   If the race is 888km long and the radius of the track is 1.414km, how many times did the car go around the track?  The race takes 2 hours and 45 minutes, what is the race car’s average velocity (in m/s) over the entire race?  What is the race car’s average speed (in m/s) over the entire race?

An athlete runs two-thirds of the way around a circular track of radius 50 m. Determine (a.) her displacement relative to her start point, and (b.) her total distance traveled.

A truck starts out at position x = 3.2 mi and y = 6.2 mi and winds up at position x = 5.6 mi, y = 2.2 mi. Find the magnitude and direction of the truck's displacement.
