Consider a particle moving along the x-axis where x(t) is the position of the particle at time t, x′(t) is its velocity, and x′′(t) is its acceleration. A particle, initially at rest, moves along the x-axis such that its acceleration at time t > 0 is given by a(t) = 2cos⁡(t). At the time t = 0, its position is x = 7. (a) Find the velocity and position functions for the particle. v(t) = f(t) = (b) Find the values of t for which the particle is at rest. (Use k as an arbitrary non-negative integer. ) t =
