Two forces, $\vec{F}_{1}$ and $\vec{F}_{2}$, act on the $7.00$ -kg block shown in the drawing. The magnitudes of the forces are $F_{1}=59.0 \mathrm{~N}$ and $F_{2}=33.0 \mathrm{~N}$. What is the horizontal acceleration (magnitude and direction) of the block?

Key Concepts

Newton's Second Law

Newton's second law of motion establishes that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This fundamental principle is key to connecting the summed forces acting on an object to its resulting acceleration.

Vector Decomposition

Vector decomposition involves breaking a force vector into its component parts typically along orthogonal (e.g., horizontal and vertical) axes. This technique is crucial when forces are applied at angles, allowing each individual component to be analyzed separately.

Net Force Calculation

Calculating the net force involves adding all individual force vectors, taking into account both their magnitudes and directions, to obtain a single resultant force. This net force is then used in applying Newton's second law to determine the object’s acceleration.

Horizontal Acceleration

Horizontal acceleration is the acceleration component in the horizontal direction. It is obtained by focusing on the horizontal components of all forces acting on an object and applying Newton's second law, which links these net forces to the resulting acceleration along the horizontal axis.
