-- The sum of the two given forces is
44cos(60) in the x-direction
33 + 44sin(60) in the y-direction.
-- The components of the third force must be
-44cos(60) in the x-direction
-33 - 44sin(60) in the y-direction
-- The magnitude2 of the unknown force is
[-44cos(60)]2 + [-33 - 44sin(60)]2 = (484) + (5,055.94) = 5539.94
Magnitude = 74.43 newtons.
-- The angle of the third force is
tan-1 [-33-44sin(60)/-44cos(60)] = tan-1 (3.232) into the 3rd Quadrant = 72.8+180 = 252.8° .

Two forces are exerted on an object A 39 N force acts at 220degrees and a 55 N force acts at 315degrees What are the magnitude and direction of the equilibrant?
you fail in grade 11 physics
Why is the resultant of the two vectors always closer to the vector having higher magnitude?
Consider a box being pulled by two people in the top and the right direction. If the person who is pulling the box from the right is the stronger person, he exerts more force on the box [i.e, the magnitude of the force exerted toward the right is higher], it is more likely that the box will move in his direction. Quite similarly, when considering the resultant of two vectors, the resultant is bound to be closer to the higher magnitude. I hope that made sense.
When you use a hammer to drive a nail into a piece of wood are you changing the size or the direction of the force?
change the direction of force,because it exerted the force on it.
What is the resultant of two forces 4N and 5N exerted at an angle 30 degrees between them?
using parallelogram principle. 15.5N
What is the formula to find the spring constant?
F = - k x In this equation, x is the distance that the spring has been stretched or compressed away from its equilibrium position F is the restoring force exerted by the spring. k is the spring constant.
When a force on an object increases how does the object acceleration change?
Changing the magnitude or direction of forces exerted on an object changes the net force (sum of all forces) exerted on the object. The net force exerted on an object is defined as mass times acceleration (F = ma), where mass, m, is constant. This means that when the net force exerted on the object changes in magnitude (or direction), its acceleration will also change in magnitude (or direction). In addition, acceleration is defined as the change in velocity, so when the magnitude (or direction) of acceleration changes, the magnitude (or direction) of velocity will also change.
What is the force exerted by a 3kg ball?

What is the direction of the forces is the?
Is the direction where you exerted your force.
If a force is exerted to the left what direction will the reaction force be exerted?
right
When a force is exerted on a box an equal and opposite force is exerted by the box. the forces are called?

What is the meaning of drag?
Drag is something that is force exerted. It is a force that is exerted in the opposite direction of movement.
When a mass suspended from a spring is in its equilibrium position the upward force exerted by the spring is equal to the downward force exerted by gravity acting on the mass?
Yes true
