The period of vertical oscillation T of a body of mass m suspended from a light spring depends on the mass m and the force constant k of the spring.
(a) List the dimensional formulas of T, m and k.
(b) Obtain an expression for T in terms of m and k, retaining an undetermined dimensionless constant C.
(c) Experiments show that C=2π. Using this value, calculate the period when m=0.50kg and k=200Nm−1.
