(9%) Problem 2: Suppose your car was mired deeply in the mud and you wanted to use the method illustrated in the figure to pull it out. Ctheexpertta.co -a 50% Part (a) what force would you have to exert perpendicular to the center of the rope to produce a force of 11000 N on the car if the angle is 2.,00° in Newtons? & 50% Part (b) Real ropes stretch under such forces what force would be exerted on the car if the angle increases to 7.00° and you still apply the force found in part (a) to its center?Explanation / Answer
along horizontal
Fnet = 0
along vertical
Fnet = F = 2*T*sin2
F = 2*11000*sin2 = 768 N
====================
(b)
F = 2*T'*sin7
T' = F/(2*sin7)
T' = 768/(2*sin7)
T' = 3151 <<<<<-------ANSWER
