QUESTION 2 Supply all missing information with the correct numerical values. Do not include the units. Round off all answers to two decimal places. Do not forget the negative sign (-) if needed. 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 F +F2+F3=0. First, we calculate the vector sum F1 + F2 by component method. of F is The X-component 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: 7.1 17 Since we want to find F1+F2+F3-0, it follows that F3=-(F+F). Thus, %3D The magnitude of Fa is F3 - N.

QUESTION 2
Supply all missing information with the correct numerical values. Do not include the units. Round off
all answers to two decimal places. Do not forget the negative sign (-) if needed.
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
equilbrium. Find force F3 so that F + F2 +F3=0.
First, we calculate the vector sum
F +F2 by component method.
The
x-component
of F is
the
and
y-component
is
of F is
The
X-component
and
the
y-component
is
Adding the components, we can express the resultant vector in unit vector component form:
Since we want to find F +F2+ F3=0, it follows that F3 = - (F, + F2). Thus,
The magnitude of Fz is F3
%3D
N.
