Question

A train was moving at the rate of 54 kmh-1 when brakes were applied. It came to rest

within a distance of 225m. Calculate the retardation produced in the train.


​

Answer 1

Answer:

0.5

Step-by-step explanation:

FORMULA: Vf2- Vi2 = 2ad

here vf =0 and vi= 54km/h = 15 m/s and d =225 m

(0)2-(15)2 = 2 a (225)

a = 0.5 m2/s
