Consider the figure below. Arrange the kinetic energies of the final states in decreasing manner. Justify your ranking.
a.) A particle with mass m is dropped with zero initial velocity a height h above the ground, under the action of the gravitational field (acceration constant g), such that it reaches the ground (z=0) with zero potential energy and velocity v>0. Determine h, in terms of the other quantities given. b.) Another particle moves with Simple Harmonic Motion with centre O.The particle has velocity 13ms–1 when it is 3m from O and 5ms–1 when it is 5m from O.(i) Find the period and amplitude of the motion
Whenever the answer to the "is it above or below the zero reference for height?" question is Yes, then it has gravitational potential energy at that point. If the answer is No, then its gravitational potential energy at that point is zero. In the space below, draw the LOL diagram for the cart + block motion.
