Hi.
I would really appreciate it if someone could please help me with the following M1 level kinematics question as I am really stuck.
The brakes of a train can produce a retardation of 1.7 m/s^2. If the train is traveling at 100 km/h and applies its brakes what distance does it travel before stopping?
I got that:
a = -1.7
u = 22.8 (when converted to m/s)
s = ?
but I do not know where to go from here.
Thank you.
Cathy
