At position x, the accing in a of a particle P moving in a straight line is given by a=-2xcubed, where x is the distance from the origin at time t.

a) prove that the quantity (dx/dt)squared +x to the power of 4 is constant.
b) find this constant, given that the initial velocity is 0 at x=2
c) show that the motion is bounded, i.e. that the particle is constrained to oscillate within a certain interval.
d)is the motion simple harmonic? give a reason for your answer.

hi Marmoora.. i think you are in the wrong forum, i have never seen questions of this kind in this forum, all math questions lies within the known GMAT topics that is basic maths, but your questions requires knowlege about physics, i dont think you can get a definite answer from any member in this forum..
