A 237 g air-track glider is attached to a spring. The glider is pushed in 8.64 cm against the spring, then released. A student with a stopwatch finds that 14 oscillations take 13.94 s.
What is the spring constant?
Known variables:
mass m = 237 g
= 0.237 kg
time taken for 14 oscillations
= 13.94 s
Time taken for 1 oscillation
= 13.94 / 14 s
T= 0.9957 s
T= 2p v( m / k )
spring constant k
=( 2p / T ) 2 x m
= 9.437 N / m
=10 N/m
