The maximum speed of Tim is 16.95 m/s.
The given parameters:
The net force on Tim is calculated by applying Newton's second law of motion as follows;
[tex]T - \mu _k F_n = ma\\\\T - \mu _k F_n = m\frac{v}{t} \\\\T - \mu_k mg = m\frac{v}{t} \\\\t(\frac{T - \mu_k mg}{m} )= v\\\\8 (\frac{220 \ -\ 0.1 \times 71 \times 9.8}{71} ) =v \\\\ 16.95 \ m/s = v[/tex]
Thus, the maximum speed of Tim is 16.95 m/s.
