A car mass 1200kg towing a caravan mass 650kg at constant speed up a straight road inclined 8(degree) to horizontal.
Tow-bar parallel to road
Motion of car resisted by force of magnitude 200N and motion of caravan resisted by force of 400N.
Find tension in tow-bar and magnitude of driving force exerted by the car? THANK YOU!|||Hello
force exerted by the car = (650 + 1200)*g*sin8掳 + 400 + 200 N = 3125,78 N
tension in bar = 650*g*sin8掳 + 400 N = 1287,43 N
with g = 9,81 m/s^2)
