$\left(1 \;\mathrm{HP}=746 \;\mathrm{W}, \mathrm{g}=10\; \mathrm{ms}^{-2}\right)$
\(\mathrm{T}=2000 \mathrm{g}+\mathrm{f}_{\mathrm{r}}=2000+4000\)
\(\mathrm{T}=24000 \mathrm{N}\)
Power \(P=T V\)
\(\Rightarrow 60 \times 746=(24000) \mathrm{V}\)
\(\mathrm{V}=\frac{60 \times 746}{24000}=1.865 \approx 1.9 \mathrm{m} / \mathrm{s}\)
