QUESTION 1 ) What is the equation describing the motion of a mass on the end of a spring which
is stretched 10. cm from equilibrium and then released from positive amplitude.
and whose period is 0.4s?


QUESTION 2 ) A 0.900 kg mass suspended from a spring oscillates with a period of 4.00 s. If the
mass added to 3.60 kg, how long is the period ?​

Answer 1

T, start subscript, s, end subscript is the period of the spring, mmm is the mass, and kkk is the spring constant. The period of a spring-mass system is proportional to the square root of the mass and inversely proportional to the square root of the spring constant.
