I just really dont understand the wording of this question. A car of mass 1200kg tows a caravan of mass 1000kg. The frictional force on the car and caravan is 200N and 500N respectively, The Car accelerates at 2 ms^-2 b) What force does the tow bar exert on the caravan?:yuck: Does it want me to find the tension of the bar? M x A = T - Friction 4312N = T - 700N T = 3612N ?
