Answer:
The net force on the stump is 1000 N.
Explanation:
Given that,
Force 1 acting on the truck, (due north)
Force 2 acting on the truck, (due west)
We need to find the net force on the stump. We know that force is a vector quantity. The net force on the stump is given by the the resultant force. It is given by :
F = 1000 N
So, the net force on the stump is 1000 N. Hence, this is the required solution.
