Two objects are connected to cach other by a rope over a pulley as in the figure. The masses are ma = 8.00 kg and mp = 11.0kg. If initially ma is at rest 1.36 m from the edge of the table, how long does it take to reach the edge of the table if the system is allowed to move freely (i.e. with no friction)? Mg (c) 1.97s (a) 12.3s (d) 0.692 s (b) 0.413s (e) 5.38 s

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.
