- 10. A student drove to the university from her home and noted that the odometer on her car increased by 15.0 km. The trip took 17.0 min. (a) What was her average speed in km/h? _____ km/h (b) If the straight-line distance from her home to the university is 10.3 km in a direction 25.0° south of east, what was her average velocity in km/h? _____ km/h (c) If she returned home by the same path 7 h 30 min after she left, what were her average speed and velocity in km/h for the entire trip? average speed = _____ km/h average velocity = _____ km/hA pilot flies in a straight path for 1 h 30 min. She then makes a course correction, heading 10° to the right of her original course, and flies 2 h in the new direction. If she maintains a constant speed of 500 mi/h, how far is she from her starting position? (Round your answer to the nearest mile.)A person on a road trip drives a car at different constant speeds over several legs of the trip. She drives for 10.0 min at 60.0 km/h, 20.0 min at 65.0 km/h, and 30.0 min at 50.0 km/h and spends 55.0 min eating lunch and buying gas. (a) What is the total distance traveled over the entire trip (in km)? km (b) What is the average speed for the entire trip (in km/h)? km/h
- A person travels by car from one city to another with different constant speeds between pairs of cities. She drives for 30.0 min at 85.0 km/h, 17.0 min at 90.0 km/h and 55.0 min at 40.0 km/h, and spends 35.0 min eating lunch and buying gas. (a) Determine the average speed for the trip. km/h (b) Determine the distance between the initial and final cities along this route. kmProblem 2.01. A student drove to the university from her home and noted that the odome- ter reading of her car increased by 12.0 km. The trip took 18.0 min. (a) What was her average speed? (b) If the straight-line distance from her home to the university is 10.3 km in a di- rection 25.0° south of east, what was her average velocity? (c) If she returned home by the same path 7 h 30 min after she left, what were her average speed and velocity for the entire trip?Problem 3: An object is thrown off the top of a building with velocity 32 m/s at an angle of 17° with respect to the horizontal.
