A pendulum is made up of a (251.3 ± 0.1) g mass and a string which is (1.3±0.005) m long. When the mass consists of a speed of (1.3 ± 0.1) m/s at the bottom of the swing:
i) Compute the centripetal acceleration of the mass (with uncertainty).
ii) Use Newton's second law of motion to get the equation required to resolve for the tension. Note the free body diagram should be included.
iii) Compute the tension in the string (having uncertainty).
iv) Find out the centripetal force acting on the mass.
