What we know
- Mass: 100 kg
- Incline angle: 15°
- Friction coefficient (μ): 0.05
Step by step
- Given
- m = 100 kg, θ = 15°, μ = 0.05
- Formula
- T = m·g·(sin θ + μ·cos θ)
- Substitute
- T = 100 × 9.80665 × (sin 15 + 0.05 × cos 15)
- Result
- T = 301.177 N

The physics
A rope pulling a block up a slope has to fight two things: the component of gravity acting down the incline (mg·sin θ) and kinetic friction (μ·mg·cos θ), which also points down the slope while the block moves up. Add them and, for a rope parallel to the surface, T = m·g·(sin θ + μ·cos θ).
