I'm trying to help a student solve the following problem:
A 15 meter in diameter asteroid with a mass of approximately 10,000 metric tons going 20 km/s. The entry and time for disintegration was 28 seconds. Entry angle to horizontal is 18 degrees and the terminal art of the fireball was at about 25 km. What is the straight line distance the meteor traveled?
How is the angle of entry factored into the calculation of the straight line distance?
