- For a vector with components (5.2, 7.5), calculate the magnitude. Your Answer: AnswerMountain highways with long descents have “escape” roads with a steep incline for vehicles to take if their brakes have failed. If one of these roads is inclined at 34 degrees above horizontal, how long must it be to stop a truck weighing 20,000 lb that is traveling at 54 mph? Provide your answer in ft and round to the nearest whole number.A ship sails 400 miles due east. It then sails north 45 degrees West for 200 miles. Where is the ship located, distance and angle?
