The jet plane starts from rest at `s =0` and is subjected to the acceleration shown. Determine the speed of the plane when it ha

Correct Answer - A::D
From the graph,
`a=22.5-22.5/150.s or `
`int_0^v v.dv=int_0^60(22.5-22.5/150xxs)ds`
`:. v^2/2=22.5xx60-22.5/150xx(60)^2/2`
`:. v=46.47 m//s`

The jet plane starts from rest at `s =0` and is subjected to the acceleration shown. Determine the speed of the plane when it has travelled 60 m.
