Question

A train starting from a station and moves with a constant acceleration for 2 minutes. if it covers a distance of 400m in this period, find the acceleration

Answer 1

hey dear
here is your answer

given data :

initial velocity (u) = 0

time taken (t) = 2 min. or 120 seconds

distance travelled (s) = 400 meter

to find : acceleration

here we go

solution :

by using 2nd equation of motion

s = ut+1/2at²

400 = 0*120+1/2*a*(120)²

400 = 0+1/2a*14400

7200a = 400

a = 0.055 m/s²

hope it helps :)
