you seem to use different number than in the first image.
make a drawing of the forces and the components, so you can see in which direction they point and when you have to add and when to subtract them

and y
y=356sin(9) + 313cos26

sparky450r said:...how would I know when to add and subtract and which go in the X equation and the Y because I am obviously missing something here.
sparky450r said:Are you saying use cos to compute both x's and both y's. no sin?

sparky450r said:Y=356sin9-313sin26
X=356cos9+313cos26
The resultant force of two applied forces on a car is the single force that has the same effect on the car as the two original forces combined. It is the vector sum of the two forces, taking into account their magnitude and direction.
The resultant force can be calculated using the Pythagorean theorem or by using the parallelogram method. The Pythagorean theorem involves finding the square root of the sum of the squares of the two forces. The parallelogram method involves drawing a parallelogram using the two forces as adjacent sides, and the diagonal of the parallelogram represents the resultant force.
The magnitude and direction of the two applied forces are the main factors that affect the resultant force on a car. Other factors that can influence the resultant force include the geometry and weight distribution of the car, as well as any external forces such as friction or air resistance.
The resultant force determines the acceleration and direction of the car's motion. If the resultant force is zero, the car will remain at a constant velocity. If the resultant force is non-zero, the car will accelerate in the direction of the resultant force.
Yes, the resultant force can be greater than the sum of the two applied forces if the forces are acting in different directions. In this case, the resultant force will be the difference between the two forces in the direction of the larger force.
