Question

a train starting from a railway station and moving with uniform acceleration attain a speed 40 km per hour in 10 minutes find its acceleration

Answer 1

u=0 kmph
v=40 kmph
t=10 min=10/60=1/6
a= (v-u)/t=(40-0)/1/6
=40×6=240 km/hr^2

Answer 2

Solution:-

given by :-

》u = 0 , v = 40k/h = 40×5/18 =200/18= 100/9 m/s
》 , t = 10minut = 600s

》by formula:-

》acceleration(a) = (v-u)/t

》 = (100/9-0)/600

》 = 100/5400

》 = 1/54m/s^2
