Q3. A 0.500-kg mass suspended from a spring oscillates with a period of 1.50 s. How much mass must be added to the object to change the period to 2.00 s?

1. A 30 g mass is used to make a pendulum for a clock such that the period is to be 1.00 s.(a) How long must the pendulum be?(b)Would the clock keep accurate time on the Moon? If not, would it run fast or slow?

Three springs with force constants k1 = 10.0 N/m, k2 = 12.5 N/m, and k3 = 15.0 N/m are connected in parallel to a mass of 0.500 kg. The mass is then pulled to the right and released. Find the period of the motion.  a.)0.515 s       b.) 0.041 s     c.) 0.413 s       d.) 0.726 s

16. A 3.2 kg mass is attached to a hanging spring with a spring constant of 25 N/m. The mass is displaced from its equilibrium position by 5 cm and system is observed to have oscillating behavior. What is the period of the oscillating spring-mass system?
