1) A pendulum is made out of a ( 251.3+-0.1)g mass and a string that is (1.3+-0.005)m long. If the mass has a speed of (1.3+-0.1)m/s
A) Calculate the centripetal acceleration of the mass and its uncertainty
B) Use Newtons' Second law of motion to obtain the equation needed to solve for tension . (Note the free body diagram must be included)
C) Calculate the tension of the string and its uncertainty
D) Determine the centripetal force acting on the mass and its uncertainty help?
