Answer :
2.25 joules work is done in stretching the spring from its natural length to 90 cm beyond its natural length.
How can determine a spring's natural length?
The spring's length without any connected mass is its natural length. Assuming the spring abides with Hooke's law The spring produces a force Fs=kL if its length is altered by an amount L from its normal length, where k is a positive quantity known as the spring constant.
distance moved = 90 cm = 0 .50 m
F = 500 N =5.00 KN
Work Done = FS = 5.00 KN * 0 .50 m
= 2.5K Joules
in stretching the spring from its natural length to 90 cm beyond its natural length is
2.5 * 0.90
2.25 joules
