Hookes law

A spring has a spring constant of 450 N/m. How far is the spring compressed if 150 N of force are used?

• 2.2 m

• 3m

• 5.0 m

• 0.3 m

A force of 400 N is applied to stretch a spring which has a spring constant, k=100 N/m. How much does the spring stretch past its free length?

• 0.4 m

• 2.34 m

• 4 m

• 5.17 m

What force should be applied to compress a spring by 0.5m if its spring constant is k = 1500 N/m?

• 1880 N

• 750 N

• 1500 N

• 3000 N

A net force of 1400 N acts to stretch an extension spring. How far will the spring stretch if its spring constant is 700 N/m?

• 1.0

• 0.5m

• 1.5 m

• 2.0 m

What Quantity can you calculate from the graph and give the magnitude of that quantity.  

• distance 4.5 m
• Force 15 N
• spring constant 20 N/m
• spring constant 200 N/m

If F is force, k is spring constant and x is extension, Hooke's Law tells us that:

• F=k/x
• x=Fk
• k=Fx
• F=kx

A spring extends 1.5m under load 10N. What is its spring constant?

• 0.15N/m
• 10N/m
• 6.7N/m
• 15N/m

_________ is the unit of Spring Constant

• N

• N/m

• m

A bungee rope has a spring constant of 5N/m. How much a person must weighs in Newton if we want it to extend (stretch) 10m?

• 20N

• 22cm

• 50N

• 50cm

• 21N
