A bullet of mass m1 = 0.020 kg is fired with initial speed v1 into a block of mass m2 = 0.500 kg that is initially at rest. The bullet becomes embedded in the block and the pair slide along to the right a distance d= 0.35 m over a rough surface with uk = 0.25. the spring (with k = 450 N/m) is compressed by a distance of x = 0.075 m. work backwards and determine the initial velocity of the bullet.

Round your answer to the nearest tenth if needed(#4 and #3 are solve for x) Pete is investigating the solubility of salt (NaCl) in water. He begins to add 50 grams of salt to 100 grams ofroom temperature tap water in a beaker. After adding all of the salt and stirring for several minutes, Petenotices a solid substance in the bottom of the beaker. Which statement best explains why there is a solidsubstance in the bottom of the beaker?A. The salt he is using is not soluble in water.B. The salt is changing into a new substance that is not soluble in water,C. The dissolving salt is causing impurities in the water to precipitate to the bottomD. The water is saturated and the remaining salt precipitates to the bottom Henry mixed salt and water together in a cup until he observed a clear solution. He measured the mass of the solution. Then he placed the cup outside for several sunny days during the summer. After a week, he observed that only solid salt remained in the cup and the mass had decreased. Henry concluded that a physical and chemical change occurred in this investigation.Which statements correctly defend or dispute his conclusion?He is correct. Dissolving salt in water is a physical change, but evaporating the water is a chemical change. Formation of a solid is evidence that a chemical change occurred.He is correct. Evaporation is a physical change, but dissolving salt in water is a chemical change. The change in mass is evidence that a chemical change occurred.He is incorrect. Dissolving salt in water and evaporation of the water are both physical changes. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change.He is incorrect. Dissolving salt in water and evaporation of the water are both chemical Zwhat type of economic system of government in eastern Europe lead to the employer use of resources Sum of 5x^2+2x and 4-x^2 A club raised 175% of it goal for a charity.
