Answer 1

Answer:

centripetal acceleration,a=40m/s^2

Explanation:

________________________________

centripetal acceleration,a is given by,

$a = \frac{ {v}^{2} }{r}$

________________________________

given,

v=720km/hr=720×(5/18)m/s=200m/s

r=1km=1000m

________________________________

therefore,

$a = \frac{ {200}^{2} }{1000} \\ \: \: = \frac{200 \times 200}{1000} \\ \: \: = 40$
