Sorry for not posting on subjects board - there hasn't been much activity on there recently....anyway here's the question.....
A car, of mass 1000kg, tows a caravan of mass 700kg along a straiht horizontal road. The force produced by the engine of the car is 3500N and the resistances to motion acting on the car and caravn are 650N and 320N respectively. Determine:
a) the acceleration of the car and caravan
b) the tension in the towbar
Could anyone plz check if the following solution is right....?
a) 3500 - 650 = 1000a
=> 2850 = 1000
b) T -320 = 700(2.85)
Your solution is wrong
If you use tension in part (a):
1) + 2):
From there you can work out part (b)
Yeah I just realised. Thanks anyway for replying
