A ball rolls on a circular track of radius 0.68 m with a constant angular speed of 2.6 rad/s in the counterclockwise direction. If the angular position of the ball at t = 0 is θ = 0, find the x component of the ball's position at the times 2.5 s, 5.0 s, and 7.5 s. Let θ = 0 correspond to the positive x direction
