A230 g air-track glider is attached to a spring. the glider is pushed in 8.2 cm and released. a student with a stopwatch finds that 13 oscillations take 19.0 s . what is the spring constant? express your answer using two significant figures.

4.3 N/m

Explanation:

m = 230 g = 0.230 kg, x = 8.2 cm

in 13 oscillations, time taken = 19 s

In 1 oscillation, time taken = 19 / 13 = 1.46 s

By the use of formula of time period , Let k be the spring constant.

0.054 = 0.230 / k

k = 4.26 N/m

k = 4.3 N/m

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
