Osler, T. J.; Chandrupatla, T. R. – International Journal of Mathematical Education in Science & Technology, 2006

The paper shows how a reasonable assumption, based on experience with simple harmonic motion, allows one to greatly simplify such problems. Proposed solutions involve only mathematics available to students from first year calculus.
