In this problem we are going to consider two different examples of the dot product between two vectors, a force F and a displacement delta r.  (a) if the force vector has a magnitude of F= 19 N, The displacement has a length of deltas=1.2 m, and the angle between the vectors is 35°, what will the dot product between the vector F and the vector delta r be? You can answer in Joules (which is the same as Newton meters) . (B) if the force vector has components fx =8.5 N and F y=12 N,  and the displacement factor has components delta rx=0.15 m and delta ry=0.61m, what is the dot product between them? Again, enter the answer in joules.
