**drwls**, Monday, October 18, 2010 at 11:43amThe scalar "dot" product of the Force F and the displacement d,

F*d = |F||d| cos theta.

equals the work done, which equals the kinetic energy increase.

Use that fact to compute the cosine of theta, the angle between the two vectors.

The magnitude of F, represented by |F|, is 14N.

The magnitude of d is sqrt29 = 5.39 m
