A student runs 30.0 m at 70.0° south of west. He then runs 5.00 m at 20.0° south of west. He then turns and runs an additional 12.0 meters at 15.0° north of west and hides in his room. What is the total displacement of the student? (Our chapter name is called Two-Dimensional Kinematics so please show me how to do this problem using the two-dimensional kinematis equations)

A runner is training for an upcoming marathon by running around a 112-m-diameter circular track at constant speed. Let a coordinate system have its origin at the center of the circle with the x-axis pointing east and the y-axis north. The runner starts at (x, y) = (56 m, 0 m) and runs 2.5 times around the track in a clockwise direction. What is the magnitude of his displacement vector? ............. Whar is the direction of his displacement vector? West...

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...

17. Two runners start running in the same direction at the same instant, t- 0.00. Runner A starts from a point that is 20.0 meters in front of runner B. Runner A starts with and maintains a constant acceleration of 2.00 m/s for 3.00 seconds, and then runs at a constant velocity. Runner B starts with and maintains a constant acceleration of 2.20 m/s for 4.0 seconds, and then runs at a constant velocity. a. Calculate the time when runner...
