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.

The figure below shows an experiment with two marbles. Marble A was launched towards marble B with launch angle a and initial speed vo = |vo| > 0. At the same instant, marble B was released to fall from rest at Rtan a units directly above a spot R units horizontally downrange from A. Show that the marbles collide regardless of the initial speed vo. B R tan a -----
In the design of a timing mechanism, the motion of pin P in the fixed circular slot is controlled by the guide A, which is being elevated by its lead screw. Guide A starts from rest with pin P at the lowest point in the circular slot, and accelerates upward at a constant rate until it reaches a speed of 90 mm/s at the halfway point of its vertical displacement. The guide then decelerates at a constant rate and comes to a stop with pin P at the uppermost point in the circular slot. Determine the n- and t-components of acceleration of pin P once the pin has traveled 23° around the slot from the starting position.
In the following exercise, we will assume that motion going from left-hand-side to right-hand-side will have positive algebraic velocities. VA M.S-1 A VB M.S-1 B Ball A has a mass of 8-kg and is moving with a speed of 9 m.s¹ when it makes a direct collision with ball B, which has a mass of 2 kg and is moving with a speed of 1 m.s´¹ The collision is not elastive. If e = 0.5, determine the velocity of B (if it goes towards left-hand-side, set negative a negative value) just after the collision -1
