A BLOCK OF MASS m RESTS ON A FIXED SURFACE AS SHOWN IN THE FIGURE. THE DOUGH IS PUSHED TO THE RIGHT AND THE SPRING IS COMPRESSED A DISTANCE d. THE SPRING IS NOT ATTACHED TO THE BLOCK. IF THE BODY IS RELEASED FROM REST, APPLYING NEWTON'S SECOND LAW DETERMINE: A)THE EXPRESSION OF THE IMPACT VELOCITY OF m WITH M1 AT THE END OF THE DISTANCE TRAVELED S. B)SUPPOSE THAT AFTER THE IMPACT EACH MASS HAD A DISPLACEMENT S1 AND S2 RESPECTIVELY. FIND SPEEDS AFTER IMPACT.

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.
