A camera on the left edge of a circular track of radius D = 4 m tracks a particle as it travels around the circle. The polar equation of the path is given above. At the moment shown, the camera angle is 0 = 30, and the camera is rotating at 0 = 0.5 rad/s, which is accelerating at a rate 0 = -0.1 rad/s. What is the velocity, acceleration, and rate of change of speed of the particle at that instant? v = a = m/s m/s v = m/s 0 T = D cos(0) A camera on the left edge of a circular track of radius D = 4 m tracks a particle as it travels around the circle.
