The keys on a computer keyboard contain small springs that compress by 4.8 mm when a key is pressed. On a particular day, 12,500 keystrokes are made on the keyboard. The springs in the keys each have a constant of 2.5 N/m. How much energy was supplied to make all the keystrokes performed that day?
A spring with a constant of 16 N/m has 98 J of energy stored in it when it is extended. How far is the spring extended?
A spring has 50 J of energy stored in it when it is extended by 2.5 m. What is the spring’s constant?
