A simple pendulum of length L = 1 m oscillates with its angular displacement as function of time given by θ(t)=10°cos⁡(πt ‒ π/2). At time t = 2T/3, where T is the period of oscillation, the values the velocity and tangential acceleration are:


v = ‒ (√3/2) v_max , and a_t = ‒ (1/2) a_max

v = 0, and a_t = ‒ a_max

v = ‒ (1/2) v_max ), and a_t = + (√3/2) a_max

v = (√3/2) v_max , and a_t = ‒ (1/2) a_max

v = ‒ (1/2) v_max ), and a_t = ‒ (√3/2) a_max
