Question

Two blocks of ice are at rest on a smooth frozen lake. One block is 3 times the mass of the other block. A man pushes each block the same distance, d meters with an equal force. Which of the statements about the kinetic energy of the heavier block is true?

1. The kinetic energy of the heavier block is smaller than the kinetic energy of the lighter block.

2. The kinetic energy of the heavier block is greater than the kinetic energy of the lighter block.

3. The kinetic energy of the heavier block is equal to the kinetic energy of the lighter block.

4. It cannot be determined without knowing the force and the mass of each block.

Explanation / Answer

kinetic energy would be equal . since work done by man is same on both the block and the all the wormk is translated into kinetic energy of blocks. since it was smooth surface there was no loss of energy due to friction as well.
