A woman weighing 670 N does a pushup from her knees, as shown in the figure. (Figure 1) Part A What are the normal forces of the floor on each of her hands? Express your answer to two significant figures and include the appropriate units. Part B What are the normal forces of the floor on each of her knees? Express your answer to two significant figures and include the appropriate units.

Researchers often use force plates to measure the forces that people exert against the floor during movement. A force plate works like a bathroom scale, but it keeps a record of how the reading changes with time. (Figure 1) shows the data from a force plate as a woman jumps straight up and then lands. Suppose that Delta t = 0.24s.
