ANSWER:
Solution 94GP
Step 1 of 3
Part a
We are required to calculate the distance moved by the blocks. This can be done using the principle of conservation of energy.
Initially both the blocks are moving with the same speed.
So, the kinetic energy of the system is,
Finally the blocks come to rest. So, their kinetic energy is zero.
The block moves by a distance of
.
Thus, the potential energy,
Now, using conservation of energy,
The required distance is .
