there are 2 blocks along a frictionless track. block 1 has a mass of m1 and block 2 has a mass of m2. Block 1 is initially moving at a speed of v0. it collides and sticks to the initial stationary block 2. (m2=9m1) what fraction of the inital kinetic energ of the system is converted to other forms (heat, sound...) as a result of the collision?

1)1%

2)10%

3)50%

4)90%

5)95%

2. Relevant equations

I sort of think this as more of a general knowledge question... this is the 2nd part. the first part ask you to calculate the velocity after collision

3. The attempt at a solution
