the time T for a pendulum to swing back and forth once is called its period and is given by T=2(3.14)sqrt L/g where L equals the length of the pendulum solve for g.
a. solve the formula for g
b. use the table to determine the value of g(the units for g are feet per second
L .5 1.0 1.5
T .78 1.11 1.36
c. interpret your result
