G 4. A particle moves along the x-axis with acceleration a(z) = 20 cost (esin)-18. If the particle is moving left with speed = 10 at t = 0, describe the motion of the particle at t= A) moving right, speeding up C) moving left, speeding up 2 B) moving right, slowing down D) moving left, slowing down A particle moves along the x-axis so that its velocity at any time > 0 is given by v(t)=413-8 What is
