what is distance when time is 5 sec acceleration is 4 ms square initial velocity is 20 m/s and final velocity is 40 m/s |

Answer» ata : Time is 5 sec, acceleration is 4 m/s², initial velocity is 20 m/s and final velocity is 40 m/s.To find : The distance ?Solution : Now, we use kinematical equation ⟹ s = u * t + ½ * a * t²{ Where, v = final velocityu = initial velocitya = acceleration t = time taken by particle s = distance covered by particle } Now, by formula⟹ s = u * t + ½ * a * t²⟹ s = 20 * 5 + ½ * 4 * 5²⟹ s = 40 + ½ * 4 * 25 ⟹ s = 40 + 2 * 25 ⟹ s = 40 + 50 ⟹ s = 90 m ANSWER : Hence, the distance is 90 m.Learn more :a train starts from rest with an acceleration of 2m/s a MAN who is 9m behind the train runs with UNIFORM speed and just... brainly.in/question/27255755A train has to cover 360 km in 6 hours.
