Question

A train travelling at 20m/s undergoes a uniform retardation of 2m/s when the break are applied calculate the time taken when it comes to rest and the distance travelled from the place where the breaks are applied

Answer 1

v = 20 - 2t
t = 10 s
s(t) = 20t - t^2
s(10) = 20*10 - 10^2 = 100 m

Answer 2

True
