Quizplus · Accepted Answer

The force required to prevent the trailer from rolling down the ramp is equal to the force of gravity pulling the trailer down the ramp. This force is equal to the weight of the trailer multiplied by the sine of the angle of the ramp. 
Force = weight x sin(angle) 
= 11,854 x sin(11) 
= 2,084.23 
Rounding to two decimal places, the answer is approximately 2,084.23 pounds, which is closest to choice A.
