Three forces act simultaneously on point J. One force is 20.0 N north; the second is 20.0 N west; the third is 10.0 N 60° east of north. Determine the magnitude and direction of the resultant force.
The formula for calculating the resultant force at J is FJ = √(Fx2 + Fy2).
The direction of the resultant force at J can be determined by calculating the angle θ using the formula tan θ = Fy/Fx.
Yes, the resultant force at J can be negative if the forces acting on the object are in opposite directions. This indicates that the net force is in the opposite direction of the initial forces.
The resultant force at J is typically measured in units of Newtons (N), which is the standard unit for force in the International System of Units (SI).
Calculating the resultant force at J is important in determining the overall effect of multiple forces acting on an object. It helps us understand the direction and magnitude of the net force, which is crucial in predicting the motion of the object.
