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.

In the figure, masses of a sphere of radius r and mass m are compressed between two neglected rods. The length of the bars is indicated by l, and the angle they make with the vertical by the angle. The force applied from the ends of the rods is in the horizontal direction and its magnitude is given by P. Friction between sphere and rods is neglected. Therefore, find the acceleration of the sphere in the vertical direction when the angle is 30º in terms of the given magnitudes. Note: Treat the sphere as the material point.

The 150-g hockey puck initially rests on a surface at A with the spring compressed by 0.2 m, as shown. The kinetic friction coefficient between the surface and the puck is ?? = 0.1. The puck is in contact with the spring but is not attached to it. Subsequently, the spring is released. Determine the minimum stiffness of the spring so that the puck just clears the wall at B.
