A bicycle is experiencing a range of forces. 65N of gravity downwards. 65N of normal force upwards. 108N of applied force forwards. 36N of friction backwards. 40N of wind resistance backwards.
Calculate the net force for both forwards and backwards, and upwards and downwards for the bicycle described.
Upwards/downwards net force = 0N
forwards/backwards net force = 32N
