Show complete solutions. Please draw the figure or the illustrations. Problem: Two horses are pulling a barge with mass 2000 kg along a canal, as shown in the Figure. The cable connected to the first horse makes an angle of 30o with respect to the direction of the canal, while the cable connected to the second horse makes an angle of 45.0o. Find the initial acceleration of the barge, starting at rest, if each horse exerts a force of magnitude 600 N on the barge. Ignore forces of resistance on the barge.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
