Suppose that two boys pull a sled with forces of 2.0 x 104 N at a 15° angle to the left of the center of the sled, and 1.8 x 104 N at an angle of 25° to the right of the center of the sled, respectively.
If the sled does not move, what is the other force that must be acting on the sled?
a. 2.1 x 104 N at 260°
b. 2.1 x 104 N at 290°
c. 3.6 x 104 N at 266°
d. 3.6 x 104 N at 282°
