A particle (mass = 0.40 kg) moves in one dimension (x) and the potential energy is V(x) = (?1/2) q x2 with q = 7.35 J/m2. The initial conditions at t = 0 are velocity = 0 and position x0 = 2.9 m.(A) What is the force?(B) Solve for the motion of the particle, from conservation of energy. x(t) has the form A cosh(?t). Calculate the value of ?.(C) Calculate the time t when x = 2 x0.
