In the system of two blocks and a spring shown above, blocks 1 and 2 are connected by a string that passes over a pulley. The initially un-stretched spring connects block 1 to a rigid wall. Block 1 is released from rest, initially slides to the right, and is eventually brought to rest by the spring and by friction on the horizontal surface.
Which of the following is true of the energy of the system during this process?


Sagot :

Potential energy lost by block 2 is greater than the potential energy gained by the spring - is true of the energy of the system during this process

What is potential energy?

Potential energy is stored energy that is affected by the relative location of various components in a system. Stretching or compressing a spring increases its potential energy. A steel ball has higher potential energy when lifted above ground than when it falls to Earth.

Because every item moved from its resting posture has stored energy, it is referred to as potential energy because it has the ability to accomplish work when released.

Thus, potential energy lost by the block 2 = potential energy gained by the spring + energy lost to overcome the friction.

Thus, Potential energy lost by block 2 is greater than the potential energy gained by the spring .

The initially unstretched spring connects block 1 to a rigid wall. Block 1 is released from rest, initially slides to the right, and is eventually brought to rest by the spring and by friction of the horizontal surface. 24. Which of the following is true of the energy of the system during this process? (A) The total mechanical energy of the system is conserved. (B) The total mechanical energy of the system increases. (C) The energy lost to friction is equal to the gain in the potential energy of the spring, (D) The potential energy lost by block 2 is less in magnitude than the potential energy gained by the spring. (E) The potential energy lost by block 2 is greater in magnitude than the potential energy gained by the spring.
