a particle starting from rest revolves with uniformly increasing speed in a clockwise circle in the xy plane. The center of the circle is at the origin of an xy coordinate system. At t=0, the particle is at x=0.0, y=2.0 m. At t=2.0s the particle has made one-quarter revolution and is at x=2.0, y=0.0 m. Determine (a) its speed at t=2.0 s, (b) the average velocity vector, and (c) the average acceleration vector during this interval.(adsbygoogle = window.adsbygoogle || []).push({});
