Question

A plane is flying to a city 726 km directly north of its initial location. The plane maintains a speed of 198 km/h relative to the air during its flight. (a) If the plane flies through a constant headwind blowing south at 51.5 km/h, how much time (in h) will it take to reach the city? h (b) If instead the plane flies through a constant tailwind blowing at 51.5 km/h, how much time (in h) will it take to reach the city? h (c) If instead the plane flies through a constant crosswind blowing east at 51.5 km/h, how much time (in h) will it take to reach the city? h 12. A bolt drops from the ceiling of a train car that is accelerating northward at a rate of 3.25 m/s². (a) What is the acceleration of the bolt relative to the train car? m/s² at ° to the ---Select--- from the vertical (b) What is the acceleration of the bolt relative to the Earth? m/s² ---Select---
