The masses of blocks A and B are 2 kg and 3 kg respectively

The masses of blocks A and B are 2 kg and 3 kg respectively, Block A slides on the smooth surface and strikes the spring attached to stationary block B. The spring deforms during the collision process. What quantity do the blocks have in common at the instant the spring has the maximum compression? Acceleration Mechanical energy Kinetic energy Velocity Momentum

Solution

Mechanical energy is best one .energy is neither created nor destroyed it can only change the one form of energy to another form.

For getting a maximum Compression of Spring (Potential Energy =(1/2)*K*x² ) ,Initially block A have a maximum energy.
