What we know
- Mass: 25 kg
- Incline angle: 30°
- Friction coefficient (μ): 0.4
Step by step
- Given
- m = 25 kg, θ = 30°, μ = 0.4
- Formula
- T = m·g·(sin θ + μ·cos θ)
- Substitute
- T = 25 × 9.80665 × (sin 30 + 0.4 × cos 30)
- Result
- T = 207.511 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).
