A train travelling at 40km/h speeds up to 70km/h in 5sec .what is it accleration |
|
Answer» Answer: 1.65m/s Explanation: INITIAL velocity of TRAIN = 40km/h = 40*1000/60*60 = 11.11 m/s final velocity of train = 70 km/h = 70*1000/60*60 = 19.4 m/s time taken by train = 5sec acceleration (a) = v-u/t = 19.4 - 11.1/5 = 8.3/5 = 1.65 m/s follow and like |
