step 1 Hello everyone so according to this given problem we have a mass this is the mass and m is equal

Two forces, both in the x-y plane, act on a 3.25-kg mass...

Two forces, both in the $x-y$ plane, act on a $3.25-\mathrm{kg}$ mass that accelerates at $5.48 \mathrm{~m} / \mathrm{s}^{2}$ in a direction $38.0^{\circ}$ counterclockwise from the $x$-axis. One force has magnitude $8.63 \mathrm{~N}$ and points in the $+x$-direction. Find the other force.

Key Concepts

Newton's Second Law

Newton's second law states that the net force acting on an object is equal to the product of its mass and its acceleration (F_net = ma). This principle is essential for determining unknown forces when the mass and acceleration of the object are known.

Vector Decomposition

Vector decomposition involves breaking a vector into its orthogonal components, typically along the x and y axes. This technique uses trigonometric functions to express forces and accelerations in terms of their directional components, allowing for easier calculation and analysis in multi-dimensional problems.

Force Addition

Force addition is the method of combining all the individual forces acting on an object to find the net force. By summing up the forces vectorially—often via their components—one can solve for unknown forces when some of the forces are already known.

Trigonometry in Physics

Trigonometry in physics is used to relate the components of vectors through sine and cosine functions. This is crucial when converting between a vector's magnitude and its directional components, especially when dealing with forces acting at an angle.
