A spring has a natural length of 50cm. If a 60N force is required to keep the spring compressed 20cm, how much work is done during this compression? How much work is required to compress the spring to a length of 25cm?

Solutions

Expert Solution

we know that,

put F = 60N and x = 50-20 = 30 cm

now the work done is

put k = 2, x0 = 0, x1 = 50-20= 30,

and compress the spring to a length of 25 cm,

put k = 2, x0 = 0, x1 = 25,
