1. The problem statement, all variables and given/known data Pendulum of unknown length, l, has period of 9.32 seconds. Length is increased by 1 metre, and time period increases to 9.734 seconds. Calculate original length of pendulum and determine whether the experiment was conducted on earth. Hint: g is not assumed to be 9.81 ms^-2, you must find both g & l 2. Relevant equations x(t) = A1 cos vnt + A2 sin vnt? 3. The attempt at a solution Really not sure where to start, due to the two unknowns!
