1. A can of sardines is made to move along an x axis from x1 = 0.2 m to x2 = 1.2 m by a force given by F = iF0exp(-0.5x), with x in meters and F0 = 4 N. (Here exp is the exponential function.) How much work is done on the can by the force?
W = _____J
2. What work is done by a force (in newtons) F = 3.3xi + 3.5j, with x in meters, that moves a particle from a position r1 = 2.5i + 3.5j to r2 = - 3.1i - 2.1j?
W = _____J
