Aparticle moves in a straight line with the given velocity v(t) = 2t−2 − 2 (in meters per second). find the displacement and distance traveled over the time interval [0.5, 2].

Asmall metal bar, whose initial temperature was 10° c, is dropped into a large container of boiling water. how long will it take the bar to reach 70° c if it is known that its temperature increases 2° during the first second? (the boiling temperature for water is 100° c. round your answer to one decimal place.) sec how long will it take the bar to reach 98° c? (round your answer to one decimal place.)
