Answer

6.6 kJ

Work Step by Step

We know that the work is the area under the force versus distance graph. Thus, we find: $W = \int_{x_1}^{x_2}F(x)dx $ $W = \int_{0}^{10}(\mu_k mg)dx $ $W = \int_{0}^{10}((\mu_0 + ax^2) mg)dx $ $W = mg \int_{0}^{10}(\mu_0 + ax^2)dx $ We take the integral and plug in the known values to obtain: $ W \approx 6.6 \ kJ$
