In the diagram below, a student compresses the spring in a pop-up toy a distance of 0.020 m. if 0.068 j of energy are stored in the toy, what is the toy’s spring constant? a) 120 n/m b) 170 n/m c) 225 n/m d) 340 n/m

option d) 340 N/m

Explanation:

Energy stored in the spring of the toy,

 ( given)

Where, k is the spring constant and x is the length of the string after compression.

x = 0.020 m

Then spring constant,

Thus, the spring constant of toy is 340 N/m. Correct option is d.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
