Answer:

320 N/m

Explanation:

From Hooke’s law, we deduce that

F=kx where F is applied force, k is spring constant and x is extension or compression of spring

Making k the subject of formula then

Conversion

1m equals to 100cm

Xm equals 25 cm

25/100=0.25 m

Substituting 80 N for F and 0.25m for x then

Therefore, the spring constant is equal to 320 N/m
