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.

A block of mass m slides on a horizontal rough surface head on into a spring of spring constant k = 730 N/m, as shown in Figure. When the block is x = 0.8 meter away from the spring, it has a velocity v = 4.33 m/s. When the block stops, it has compressed the spring by 6.5 cm. The coefficient of kinetic friction between the block and the surface is 0.1. What is the block's mass m (in kg)? Provide your answer with 2 decimal places. Take g = 9.81 m/s2 V
One part of an inspection system in a packaging operation uses an air blast to remove defective pieces of cardboard from the conveyor belt. The blast is initiated by a sensor and clocked so that the product is in front of the blast at just the right . The product is going to be dumped onto a shelf next to the conveyor belt. Determine the speed of the air jet required to tip the cardboard off the conveyor. The density of air is 1.10 kg/m3. The cardboard has a mass of 0.10 kg and the jet has a diameter of 10 mm.

When rowing downstream consider the following scenario. The current of the water is moving at 2 m/s in the direction you are rowing. The coefficient of drag between your boat and the water is 1.2, the area in contact with the water is 0.1 m2 and the density of the water is 1000 kg/m3. You are moving at a velocity of 4 m/s into a head wind of 4 m/s. Your coefficient of drag between you and the air is 1.4, the area in contact with the air is 0.4 m2 and the density of the air is 1.2 kg/m3. Your goal is to create a net force moving downstream that is equal to 100 N. How much force must you exert with the oar and in what direction to achieve this net force downstream?
