In this problem, you will follow a step-by-step process to develop the code to implement the ordinary Verlet in- tegrator to perform the time evolution of a one-particle system. Use the block-spring system described in part A to demonstrate the dynamics predicted by this new integrator. The block dynamics is driven by energy u(x) = 1 2 kx2 and force ~f = kxi. The initial conditions are the same: at time t = 0, the block's position and velocity are x(0) = 1 and v(0) = 0 respectively. Consider block mass m = 1 and spring constant k = 1 for this problem. This implies that the initial acceleration a(0) = 1. 1. [2 points] The ordinary Verlet integrator evolves the position of the block forward in time via the equation: x(t t) = 2x(t) x(t t) t2a(t). (1) Thus, at any time t, in addition to the current position x(t) of the block, we need access to the previous position x(t t) of the block. That is, we need to memorize the previous position of the block. To this end, add a member of type VECTOR3D called previousposition to the PARTICLE class. Provide the relevant code
