Two men decide to use their cars to pull a
truck stuck in mud. They attach ropes and
one pulls with a force of 515 N at an angle
of 31◦ with respect to the direction in which
the truck is headed, while the other car pulls
with a force of 926 N at an angle of 25◦ with
respect to the same direction. What is the net forward force exerted on
the truck in the direction it is headed?



Answer :

The net forward force =(  515 cos 31deg ) +( 926 cos 25 deg )
                                   = 441.44N                + 839.24 N
                                   = 1280.7N in truck direction
Is 1280.7N because u have 926(515) =441.44 n 839.24n.
