• 0.0125 J 
• 0.0250 J 
• 0.0625 J 
• 0.125 J

• 2.0 N/cm 
• 1.6 N/cm 
• 1.8 N/cm

A spring with a spring constant (k) of 5 N/m is stretch 0.2 m. The spring force is 

• 1 N
• 25 N
• 5.2 N
• 4.8 N

How far is a spring with k = 9 N/m stretched when a 5 kg mass is attached? 

• 0.55 m
• 5.5 m
• 1.8 m 
• 18 m
