Problem 60P

CALC? A balky cow is leaving the barn as you try harder and harder to push her back in. In coordinates with the origin at the barn door, the cow walks from x = 0 to x = 6.9 m as you apply a force with x-component Fx = -[20.0 N + (3.0 N/m)x]. How much work does the force you apply do on the cow during this displacement?

Step-by-Step Solution:
Step 1 of 3

Solution 60P x 2 Work done by a variable force is given by, W = Fdx…..(1) , where F is the force that x 1 is a function of x, x a1d x are 2nitial and final displacements. Given that, Fx = -[20.0 N + (3.0 N/m)x] x = 0, x = 6.9 m 1 2 Substituting these values...
