Atrain is travelling towards the station on a straight track. it is a certain distance from the station when the engineer applies the brakes. initially, the train is moving at 50 m/s and slows down at 2.5 m/s^2. if the train stops at the station, how far before the station did the engineer apply the brake?

500 m

Explanation:

t = Time taken

u = Initial velocity = 50 m/s

v = Final velocity = 0

s = Displacement

a = Acceleration = -2.5 m/s²

Equation of motion

Time taken by the train to stop is 20 seconds

∴ The engineer applied the brakes 500 m from the station

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

yup its correct its: c) b b
