Question

a train starts from a railway station and moving with uniform acceleration attains a speed of 40 km /hr in 10 minutes . what is acceleration

Answer 1

velocity = 40km/h = 40*5/18  =  200/18 m/s

time = 10 minute = 60 second

acceleration = velocity/time
                          
                           
acceleratoin = 1/54 m/s2
