The ii part please?

You have calculated a resultant force of 5600 N for each truck in the first part, right ?

Now truck B exerts a force of 11200 N on A. Thus, A will exert an equal force in the opposite direction.

Since the resultant is 5600 N a force of 16800 N must act to the left. (16800 - 11200 = 5600)

The weight of the truck must act vertically downwards and hence a normal force equal to the weight will act upwards.

I'll try My best =]

first Drawing is Attached , let me know if you don't get it ;)

as for the second , You calculated the Distance and you got it 1.75 m

Attached as well.

Ohh and the displacement is - 1.27 m

Why : the whole drawing is under the line and hence Nothing Cancels out and so it's -1.27 m
