Xavier runs east from the origin, and Yollanda runs north from the origin. At t =...
Sally first runs East a distance of 5 km. She then runs North for 7 km. What is the angle of Sally's final displacement vector, measured in degrees, from the East direction.
A person is walking from the origin at 15 degrees east of north for 5000m and also during their walk and also go up to 1500m. This person is trying to go to a store that is at < -3000, 4000, 1000> m, where north and east are positive. What is the displacement needed so that he can make it to the store?
An adventurous dog strays from home, runs four blocks east, three blocks north, four blocks east, four blocks north, and five blocks west. Assuming that each block is about 100 m, how far (in m) from home and in what direction (in degrees counterclockwise from the east axis) is the dog? Use a graphical method. Magnitude___762_____M Direction____________ degrees counterclockwise from the east axis I have the answer for magnitude but need help with direction.
A parade runs north for 1.8 mi then heads 20 degrees North of East for 1.4 miles. What is the magnitude of the parades final displacement? Give your answer to one decimal place.
The parade runs north for 2.5 mi then heads 20 degrees S of east for 1.7 miles. What is the magnitude of the parades final displacement? Give your answer to one decimal place.
east, then 0.8 m at 30° north of due east. Beetle 2 also makes two runs; the first is 1.6 (relative to the east direction in the range of (-180%, 180%)) of its second run if it is to end up at the new location of beetle 1?
A river flows from west to east with a speed of 3m/s. A boy swims north across the river with a speed of 2m/s relative to the water. (a) What is the speed of the boy relative to the shore? (b) What is the boys direction relative to the shore?
2. A very long, straight wire runs from west to east. The wire is 17 m long and carries a 2.6 A current that moves from west to east. a. Earth's magnetic field is approximately uniform, and is directed from south to north. At the location of the wire, the magnetic field has the strength 4.4 x 10-5 T. Calculate the magnitude and direction of the force that Earth's magnetic field applies to the wire. b. What is the magnitude...
4. Two toy remote-controlled cars start from the same position, O, at time t-0. One car, C ,travels north at 4 m/s, while the other, C2, travels west at 2 m/s. (a) After two seconds, compute the rate of change of the distance between Ci and Cz. Draw a diagram to help you answer this question and the next and clearly state the units. Simplify your answer as much as possible. (7 pts.) (b) After two seconds find the rate...
A person is running up the center of a path that goes north-south at a constant rate of 3 ft/s. If I am 7 ft from the center of the path (standing still and social distancing), find the rate at which the distance between the runner and myself is changing 4 seconds after she ran past me.
