Work done on the bread box is 0.1157 J

Explanation:

Bread box is made to move along an x axis from x=0.15m to x=1.20m means total distance covered by box is (1.20-0.15) m=1.05m.

Work done is equal to Force*distance covered

i. e;

W=F. d=e^ (-2x^2). d

=e^ (-2 (1.05) ^2). (1.05) = (0.1102). (1.05)

=0.1157J
