Answer:
When brakes are applied, the speed of train decreases from 96 kph to 48 kph in 800m. How much farther will the train move before coming to a rest? From 3rd equation of motion v^2-u^2=2as from first given v=96,u=48,s=800m a=-3.84 km/h^2 from same equation now take v as 48 , u as 0 and a as got now s= 300m to stop.
