P = ka?

The seat on a tractor is mounted on springs in order to absorb impact. The driver sits on the seat,

and the springs compress a distance of a meters, m. As the springs compress, potential energy,

p, in joules (J), is stored in them according to the equation above. The spring constant, k,

describes the strength of the springs in newtons per meter

. If the springs have a spring

how much must the springs stretch in meters, in order to store 8 J of

constant of 25,600

potential energy?
