Question

A train starting from a railway station and moving with uniform accerlation attains a speed 40km\h in 10 minutes.Find its accerlation

Answer 1

Answer:

240 km/hr^2

Explanation:

given: u= 0 km/hr.,v= 40 km/hr ..,t=10 min = 1/6 hr and a=?

using one of the three equations of motions...,

v=u+a*t..,

40=0+a*1/6

a= 240 km/hr^2 i.e a= 200/3 m/s^2
