1) A spring with a spring constant of 0.70 N/m is stretched 1.5 m. What was the force? 2) The same spring is stretched 5 m. What was the force?
3) How far will 20 N of force stretch a spring with a spring constant of 140 N/m?
4) How far will a 50 N force stretch the same spring?
5) A spring is stretched 0.15 m and the force was 1500 N. What is the spring constant?
6) A spring is stretched 0.75 m by using a force of 30 N. What is the spring constant?
7) How far will a hanging 0.400 kg object stretch a spring if its spring constant is 300 N/m?

8) A hanging 7.5 kg object stretches a spring 1.1 m. What is the spring constant?
Find the force by multiplying the mass (7.5 kg) x gravity (9.8 m/s2)
Use that to calculate the spring constant
9) A spring has a constant of 875 N/m. What hanging mass will cause this spring to stretch 4.5 m?
10) A spring with a spring constant of 25 N/m is stretched 65 cm. What was the force used?
11) A 25 N force stretches a spring 280 cm. What was the spring constant?
12) A 75 N force stretches a spring 175 cm. What was the proportionality constant?
