Answer:
0J
Explanation:
Mass of the lump M1 = 1.0 kg, initial velocity of the lump U1 = 2m/s to the right,
mass of the metal sphere M2 = 0.5kg, initial velocity of the metal sphere M2 = -4m/s to the left. using conservation law of momentum;
M1U1 + M2U2 = V (M1 + M2)
(1.0 × 2) + (0.5 × -4) = V (1 + 0.5)
2 -2 = V (1.5)
0 = V (1.5)
divide both side by 1.5
0/1.5 = V 1.5/1.5
V = 0
since final velocity after sticking together of the two masses equals zero then their combined kinetic energy will also equal to zero
1/2 V(M1 +M2)
1/2 ×0 × 1.5 = 0J

Answer:
Hitler was one of the most terrible and inhumane dictators of the 20th century. His sick intention was to rule the world and to wipe out all people he considered to be subhuman beings like Jews, gypsies or mentally underachieving persons (over 6 million people). Unfortunately many Germans fell for his and his followers demagogy and hatred. There is not enough "positive" to make up for all the destruction and harm he caused on this planet. The war he started and fortunately lost caused the split of Germany and of entire Europe into to political blocks.
