Homework Statement
Homework Equations
W=(Force component*displacement)
The Attempt at a Solution
This problem uses a graph to find the Work. So I used area equations to find the Work. From 5m to 10m the Force is constant 30N. Which is applied over a displacement of 5m. So the work done from 5m to 10m is 150J. Next, from 10m to 15m the work varries. Its initially 30N then it drops down to roughly 18N. So using a triangle, .5*(30N+18N)*(5m)=120J
Answer is 270J??
