The graph shows the net external force component F cose along the
displacement as a function of the magnitude s of the displacement.
The graph applies to a 71.6-kg ice skater. How much work does the
net force component do on the skater from (a) O to 3.00 m and (b)
3.00 m to 6.00 m? (c) If the initial speed of the skater is 2.64 m/s
when s = 0m, then what is the speed when s = 6.00 m?
