A particle is subjected to the v(x) = -Fx, where F is a constant. the particle travels from x = 0 to x =a in a time interval t0. Assume the motion of the particle can be expressed in the form x(t) = a +bt + ct^2. Find the values of a, b, and c such that the action is a minimum.
Physics makes significant contributions through advances in new technologies that arise from theoretical breakthroughs.Explain two advances?
A small bird’s wings can undergo a maximum displacement amplitude of 5.0 cm (distance from the tip of the wing to thehorizontal). If the maximum acceleration of the wings is 12 m/s^2,and we assume that the wings are undergoing simple harmonic moti..
