The vertical-axis wind turbine consists of two blades that have a parabolic shape. If the blades are originally at rest and begin to turn with a constant angular acceleration of ac = 0.5 rad/s^2, determine the magnitude of the velocity and acceleration of points A and B on the blade when t = 4s.
the verticle axis has two prabolic wings that connect at the top and bottow that are 180 degrees apart (in same plane) Point A is located in the middle of the verticle axis and has a radius of 20ft. Point B is located in the upper half of the verticle axis and has a radius of 10ft from the verticle axis.
