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.

F = (C · t²) Q14. As shown in the image below, the force acting on the box is N, where constant C = 10 and t is time in s. Determine the magnitude of the total impulse (in N.s) done by force F to the box during the period from t = 0 to t = 1.5 s. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. F Your Answer: Answer 3 5 4
2/38 The aerodynamic resistance to motion of a car is nearly proportional to the square of its velocity. Ad- ditional frictional resistance is constant, so that the acceleration of the car when coasting may be written = -C₁-C₂², where C₁ and C₂ are constants which depend on the mechanical configuration of the car. If the car has an initial velocity vo when the en- gine is disengaged, derive an expression for the dis- tance D required for the car to coast to a stop. a V.
