Tarzan `(m = 85.0 kg)` tries to cross a river by swinging on a vine . The vine is `10.0m` just and his speed at the bottom of the swing (as he just clears the water) will be `8.00 ms^(-1)` Tarzan does not know that the vine hasa breaking strenght of `1000 N` Does he make it across the river safely ?

Explanation

Let the tension at the lowest piont be T
`sum F = ma, T - mg = ma_(c)= (mv^(2))/(r )`
`T = m(g + (v^(2))/(r ))`
`= 85 xx [1.0ms^(-2) + ((8.00ms^(-1))^(2))/(10.0 m)]`
`= 1.394 kN gt 1000 N`
