Speed of 126 kilometre per hour is brought to stop at a distance of 20

1.	Speed of 126 kilometre per hour is brought to stop at a distance of 200 m what is the retardation of a company
Answer» EXPLANATION: v=0 u=126km/h s=200m=0.2km ${v}^{2} - {u}^{2} = 2as \\ = > -( {126}^{2}) = 2a \times 0.2 \\ = > a = 39690km {h}^{ - 2}$

Speed of 126 kilometre per hour is brought to stop at a distance of 200 m what is the retardation of a company

Answer»

EXPLANATION:

v=0

u=126km/h

s=200m=0.2km

${v}^{2} - {u}^{2} = 2as \\ = > -( {126}^{2}) = 2a \times 0.2 \\ = > a = 39690km {h}^{ - 2}$
