A 2.20 kg mass on a spring has displacement as a function of time given by the equation x(t)= (7.40 cm) cos [4.16 rad/s) t - 2.42 rad].
A- Find the time for one complete vibration.
B- Find the force constant of the spring.
C- Find the maximum speed of the mass.
D- Find the maximum magnitude of force on the mass.
