Fiate Siena can accelerate from 0 to 48 kph in 3.6s and from 0 to 96 kph in 10.2 s Also, under constant acceleration from rest it crosses the 0.4 km marker at as peed of 140 kph. (a)Calculate the average acceleration needed get the speed 48 kph. (b) Calculatethe average acceleration during the time it requires to go from 48 to 96 kph. (c) What constant acceleration would be required to get a speed of 140 kph over the 0.4 km run starting from rest ?

Answer

[(a) `3.7 m//s^(2)`, (b) `2.01 m//s^(2)`, (c) `1.89 m//s^(2)`]
