As part of your work out, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when u push the platform, you compress the springs. You do 80.0G of work when u compress the springs 0.200m from their uncompressed length.

a) What magnitude of force must u apply to hold the platform in this position?

b) How much additional work must you do to move the platform 0.200m farther, and what maximum force must you apply?
