- A particle moves ina two-dimensional orbit defined by:
x(t)=A(2*alpha*t - sin(alpha*t) ), y(t) = A(1-cos(alpha*t)).
(This is problem 2-30 (p. 96) from Classical Dynamics of Particles
and Systems, third edition, by J.B. Marion and S.T. Thornton.
Harcourt, Brace, Jovanovich, 1988. This is a standard textbook for
a junior-level classical mechanics class.
- Find the tangential acceleration and the normal acceleration as a
function of time.
- Determine at what times in the orbit the normal acceleration has a
