Here the negative sign shows that the x-component of the pull
F3 is in the negative x direction
(b) Let F be the resultant of the three pulls. Then the xcomponent of the F is given by Hence the net magnitude of the resultant force of the three
pulls is: And the direction of the resultant force can be calculated as: EX 4.7 A 68.5-kg skater moving initially at 2.40 m/s on rough horizontal ice comes to rest uniformly in 3.52s due to friction from
the ice. What force does the friction exert on the ska...
