# Mechanics watch

1. a cyclist travels up a slope inclinded at 4 degrees to the horizontal. the cyclist and cycle are modelled as a particle of mass 80kg. A constant air resistance force of magnitude 20N acts throughout the motion. the diagram shows the forces that are assumed to act on the particle.

A) Find the value of P,
i) when the cyclist moves at a constant speed
ii) when the cyclist accelerates at 0.2ms^-2
2. draw a free body diagram including the parallel component of their weight.

I already have one, I don’t know what to do from there

what forces are opposing their motion? if they're traveling at a constant speed, what can you day about the net result of all forces acting on the cyclist?
