*Please show solution so i know how to solve the problem.thank you for your time. The angular speed of an automobile engine is increased at aconstant rate from 1200 revs/min to 3000 revs/min in 12 seconds.(a) What is the angular acceleration in revs per minute-squared.(b) How many revs does this engine make during this 12 secondinterval. *Please show solution so i know how to solve the problem.thank you for your time. The angular speed of an automobile engine is increased at aconstant rate from 1200 revs/min to 3000 revs/min in 12 seconds.(a) What is the angular acceleration in revs per minute-squared.(b) How many revs does this engine make during this 12 secondinterval.

Explanation / Answer

Given that             o = 1200 rev / min = 20 rev / s             1 = 3000 rev / min = 50 rev / s              t = 12 s (a)   = [ 1 - o ] / t =[50 - 2 0 ] / 12 = 2.5 rev /s2 = 9000rev / min2 (b) n =   [50 - 20 ] * 12 = 30 *12 = 360 rev.
