Question

Mr. One is pushing a cart with a force of F1 = 15.00 N due north. Mr. Two is pushing the same cart with a force of F2 = 25.00 N due northeast. Mr. Three is pushing the cart a force F3 so that the cart is in equilibrium. Find force F3 so that:

Mr. One is pushing a cart with a force of F1 = 15.00 N due north. Mr. Two is pushing the same cart with a force of F2 = 25.00N due northeast. Mr. Three is pushing the
cart a force F3 so that the cart is in equilibrium. Find force F3 so that F1 +F2+ F3=0.
First, we calculate the vector sum F1 + F2 by component method.
The x-component of Fi is
and the y-component is
The x-component of F2 is
and the y-component is
Adding the components, we can express the resultant vector in unit vector component form:
Fi+F2=
Î +
Since we want to find F1 + F2+ F3= 0, it follows that F3 = - (Fi + Fɔ). Thus,
F3 =
The magnitude of F3 is F3 =
N.
