SUMMARY
The required horizontal force to push a 7.3 kg shopping cart up a 13° incline with an acceleration of 1.67 m/s² is determined using the principles of physics. The applied force must be horizontal, which is crucial for calculating the net force acting on the cart. The solution involves resolving the forces acting on the cart and applying Newton's second law. The final answer is derived from the correct application of force equations relevant to inclined planes.
