a train starting from rest attains a velocity of 90 km per hour in 2 m

1.	a train starting from rest attains a velocity of 90 km per hour in 2 minutes then what will be distance traveled by train in this time. ( answer in km)
Answer» ANSWER: USING s=ut+a/2 x t^2 and v=u+at 90=0+a x 2 => a=45km/minute^2 s=0+45/2 x 4 => s= 90km

Answer»

USING s=ut+a/2 x t^2

and v=u+at

90=0+a x 2

=> a=45km/minute^2

s=0+45/2 x 4

=> s= 90km
