2) A sprig with a length of 15 cm and stores 110 J of potential energy when stretched to a new
length
If the sprig constant is 350 N/m. Find the new length of that spring

94.28 cm

Explanation:

The formula for elastic potential energy is given as;

PEel = 1/2 *k*x² where x is the displacement, k is the spring constant

Given

PEel = 110 J, k= 350 N/m  then find x

PEel = 1/2 *k*x²

110 = 1/2 * 350 * x²

110 = 175 x²

110/175 = x²

0.6286=x²

√0.6286 =x

0.7928 m = x

79.28 cm = x

New length of spring = 15 cm + 79.28 cm = 94.28 cm

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
