The route followed by a hiker consists of three displacement vectors , , and . vector is along a measured trail and is 1550 m in a direction 27.0° north of east. vector is not along a measured trail, but the hiker uses a compass and knows that the direction is 41.0° east of south. similarly, the direction of vector is 29.0° north of west. the hiker ends up back where she started, so the resultant displacement is zero, or + + = 0. find the magnitudes of vector and vector .

Acar traveling at a constant speed of 22.0 m/s passes a trooper hidden behind a billboard. one second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 3.50 m/s2. how long does it take the trooper to overtake the speeding car? solve this problem by a graphical method. on the same graph, plot position versus time for the car and the trooper.
