1.A particle moving with a velocity of 6m/s upward is subjected to anacceleration of 3m/s2 downward until its displacement is2m below its position when the acceleration began. Theacceleration then ceases for 3 s. The particle is thensubjected to an acceleration of 4m/s2 upward for 5s. Determine that displacement and the distance traveled.
2.The price of oil in 2005 was $67 per barrel. "This priceis still lower than price of in 1981" says a government publication. If inflation has average 3.2% per year from 1981 to2005, what was the price per barrel of oil in 1981?
