11) a) A particle moves counterclockwise along a circular path of radius r=6.00cm at a constant speed.
It completes one revolution in 55.00s. The particle started (x,y)=(0,-r) at t=0. Determine the position,
velocity, and acceleration vectors at t=10.00s. Express your results in unit vector notation.
b) A particle moves clockwise along a circular path of radius r=3.00cm at a constant speed. It
completes one revolution in
39.00s. The particle started (x,y)=(r,0) at t=0. Determine the position, velocity, and acceleration
vectors at t=10.00s. Express
your results in unit vector notation.
