Question

You put a ball on the end of a string. You swing the ball

Answer 1

Answer:

$19.6 ms^{-2}$

Explanation:

By the definition of  centripetal acceleration ,

$a_c=\frac{V^{2} }{r}$

where ,

a =  centripetal acceleration

V= velocity

r =  radius of circle

$a_c=\frac{V^{2} }{r}[\\a_c=\frac{5.6^{2} }{1.6} \\=19.6 ms^{-2}$
