Problem if a cyclist of mass 850 kg including the bicycle, Ask an Expert

Academics

Problem: If a cyclist of mass 85.0 kg (including the bicycle) can coast down a 1.10Â° slope at a steady speed of 24.5 km/h because of air resistance,

Part A: How much force must be applied to climb the slope at the same speed (and the same air resistance)?

I need help to find how much force must be applied to climb the slope.
