Q2 A small marble at point A of mass 0.5 kg as shown in Figure Q2 is release downward with an initial speed of VĄ m/s and strikes a smooth inclined plane given tan 0 = ² at point B. (a) If point A is located 1 m above the impact area, calculate the speed of the marble immediately before the impact. (b) Assuming the coefficient of restitution between marble and plane is e = 0.5, determine the speed and direction of the marble immediately after the impact. (c) Using the speed obtained in Q2 (b) and assuming a free flight motion of the marble after the impact. Predict the horizontal travel distance measuring from point B. VA = 2ms-1

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.
