A pendulum is 0.864 m long and the bob has a mass of 1.04 kg. When the string makes an angle of θ= 14.8 degrees with the vertical, the bob is moving at 1.44 m/s. Find the tangential and radial acceleration components and the tension in the string. (Hint: Draw an FBD for the bob. Choose the x-axis to be tangential to the motion of the bob and the y-axis to be radial. Apply Newton's second law.) at = ______...
