Distance covered by a train is 72 km with initial velocity of 20 m/s in 30 minutes. Find it's acceleration
Asked by mohapatranihar60 | 07 Nov, 2021, 12:18: PM
We use the following equation of motion to get acceleration a from given distance S, initial speed u and time duration t of travel .

S = u t + (1/2) a t2

By substituting relavant values in above equation, we get

72000 = 20 ×1800 + ( 0.5 × a × 1800 × 1800 )

By solving above expression, we get a = ( 1/45 ) m/s2
