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 10.1-Mg truck is resting on the deck of a barge which displaces 209 Mg and is at rest in still water. If the truck starts and drives toward the bow at a speed relative to the barge Vrel = 7.8 km/h, calculate the speed v of the barge. The resistance to the motion of the barge through the water is negligible at low speeds. 209 Mg Answer: v= i 7.8 km/h 10.1 Mg km/h
Q5) The 50-kg crate shown rests on a rough horizontal surface for which the coefficient of kinetic friction is #x=0.3. An electrically powered winch is utilized to accelerate the crate at a constant rate until it attains a speed of v-Sm's within a distance of s=20m. If the motor and the winch have an efficiency of n-0.70, determine the power that must be supplied to the motor when s= 20 m. 20 m 50 kg D
It takes 34 s for the 60-Mg tugboat to increase its speed uniformly to 25 km/h, starting from rest. The propeller provides the propulsion force F which gives the tugboat forward motion, whereas the barge moves freely. The barge has a mass of 84 Mg . (A) Determine the force of the rope on the tugboat. Express your answer to three significant figures and include the appropriate units. (B) Also, determine F acting on the tugboat. Express your answer to three significant figures and include the appropriate units.
