A train is traveling at a speed of 90km/h brakes are applied so as to ...
Given data:
Initial velocity, u = 90 km/h = 25 m/s
Acceleration, a = -0.5 m/s^2 (negative because the train is decelerating)
Final velocity, v = 0 (train comes to rest)
We need to find the distance traveled by the train before coming to rest.
Calculating time taken to stop:
Using the equation of motion:
v = u + at
0 = 25 + (-0.5)t
0 = 25 - 0.5t
0.5t = 25
t = 50 seconds
Calculating distance traveled:
Using the equation of motion:
s = ut + (1/2)at^2
s = 25*50 + (1/2)(-0.5)(50)^2
s = 1250 - 625
s = 625 meters
Therefore, the train will travel 625 meters before coming to rest.
