"Energy and Momentum" is always conserved in an inelastic condition
Hope this helps!
Vertebrate is the answer I think.
0.0024
Milimetres are before centimetres and centimetres are before metres
Velocity is the measurement of time of distance between point "A" and "B".
Speed, regards to how far a subject travels in "X" amount of time, disregarding an end and beginning point.
I hope this helps! :)
Momentum is conserved. Remember, p = mv, momentum = mass times velocity, and the mass of the bulled is 10 g = 0.010 kg. And the mass of both blocks is 500 g = 0.500 kg. So the momentum of the bullet is (0.010 kg)(400 m/s) = 4.00 kg m/s. Given that the first block moves at a speed of 6.0 m/s after impact. So the momentum of the first block is (0.500 kg)(6.00 m/s) = 3.00 kg m/s. So, the momentum of the second block after the bullet hits is 4.00 kg m/s - 3.00 kg m/s = 1.00 kg m/s. And dividing by its mass gives its speed. But since the bullet embeds itself in the block, its mass is the mass of the bullet plus the mass of the block, so it has become 510 g = 0.510 kg.
So the speed of the second block after impact is (1.00 kg m/s)/(0.510 kg) = 1.96 m/s. Hope you got it
