Two tractors pull against a 1000 kg log. if the angle of the tractors' chains in relation to each other is 18.0° (each 9.0° from being parallel with the log) , and each tractor pulls with a force of 800 n, what forces will they be able to exert? a. 250 nb. 1520 nc. 1580 nd. 1600 ni'm 80% sure it's c but i don't know how to go about calculating the answer. any is appreciated.
