1. The problem statement, all variables and given/known data A block is acted on by a force that varies as (1.4*10^4N/m)x for 0<x<.21m , and then remains constant at 2940N for larger x. How much work does the force do on the block in moving it from x= 0 to x= 0.30m? How much work does the force do on the block in moving it from x= 0.10m to x= 0.40m? 2. Relevant equations 3. The attempt at a solution I am not understanding the question or something. Can someone help me with the equation?
