1. A vector 11 has a magnitude of 58.0 m and points in a direction 20.0 below the positive x axis. A second vector, B, has a magnitude of 70.0 m and points in a direction 46.0\" above the positive X axis. Find the magnitude of the vector 5 = A B. m 2. Three vectors ,1, R and C are shown in the gure. The x-axis and v-axis are marked in increments of 1.00 m. Determine the magnitude of the vector D = A E + C m 3. Consider the following three displacement vectors: Vector 21' has a magnitude of 3.80 km and a direction that makes an angle of 24.0 north of east, vector 1% has a magnitude of 6.80 km and a direction that makes an angle of 33.0\" north of west, and vector 5' is unknown. Determine the magnitude of the vector 5' sothat++a=0 km 4. Consider the following three displacement vectors: Vector 41 has a magnitude of 3.80 km and a direction that makes an angle of 29.0 north of east, vector 1% has a magnitude of 7.30 km and a direction that makes an angle of 27.0\" north of east, vector 0 has a magnitude of 4.20 km and a direction that makes an ; angle of 44.0\" south of east. Determine the magnitude of the vector 55 = E + C A km 5. Two cars are traveling along a straight road. Car (A) maintains a constant speed of 88.0 km/h; car (B) maintains a constant speed of 106 kmfh. At t = 0, car (B) is 35.0 km behind car A. How far will car (A) travel from t = 0 before it is overtaken by car (B)? km
