An aircraft executes a horizontal loop of radius 500m with a uniform speed of 5 machs. Compare its centripetal acceleration with acceleration due to gravity.

Explanation

`r=500m,v=5machs=5xx330ms^(-1)=1650ms^(-1)`
We know that `a=(v^2)/r=(1650xx1650)/(500)=5.445ms^(-2)`
Hence `(a_r)/g=(5.445)/(9.8)~~(27)/(49)`
`a_r:g: :27:49`
