Homework Statement
A bike and its rider have a total mass of 86kg. If the rider is coasting on level ground at 9m/s and a 40N head wind acts on the rider for 12 seconds. What is the final velocity of the rider?
Homework Equations
The Attempt at a Solution
Assumption (Converting the Air resistance to velocity) : 40N x 12s = 480
480/86kg= 5.58m/s
9m/s - 5.58m/s = 3.42m/s is this correct or am I using the wrong equations
