PERIODIC MOTION 'l_ A 0.50kg object vibrates at the end of a vertical spring (k: 82N/m). What is the period of its vibration? 2_ When a mass of 25 grams is attached to a certain spring, it makes 20 complete vibrations in 4 seconds. What is the spring constant of the spring in N/m? 0 24.67 N/m 0 45.67 N/m 5 If an oscillating mass has a frequency of 1.25 Hz, It makes 100 oscillations in: 4_ An 8.8N object vibrates at the end of a horizontal spring along a frictionless surface. IF the period of vibration is 1.13, what is the spring constant? 5. It takes 200 N to stretch a spring by 40cm. How much force is required to stretch a spring by 120 cm? 0 600N O 700N O BOON O 500N 6_ A 1.00kg object vibrates at the end of a vertical spring. If the frequency of the vibration is 1.25Hz, what is the spring constant? 7_ How much force is required to stretch a 300 N/m spring by 25 cm? How far can you compress the spring with a force of 150 N? O force=75N,x=50 O force=85N,x=50 O force=55N,x=55 0 force: 65 N,x= 60
