A long stick rests on the surface a person standing 10 m away the stick with what minimum speed an object of masss 0.5 kg should he throuwn so that it hits the stick (Assume the coefficient of kinetic friction is 0.7 )

Explanation

Given : `r= 10 m`
`mu_(k ) = 0.7`
`m = 0.5 `
Minimum speed
`V= sqrt(2mugr)`
`=sqrt(2xx 0.7 xx 9 .8 xx 10)`
`=14sqrt(0.7)`
`V= 11.71 m//s`
