Jean-Paul is racing in the Tour de France bicycle race. He is moving along rapidly at a speed of 15 kilometers per hour. Suddenly, a strong wind begins to blow into his face. Jean-Paul cannot exert any more force on the pedals. What will happen to Jean-Paul's speed while the wind continues to blow against him?
If the air resist his motion continuously, speed of Jean - Paul get reduced until he could apply an equal force in opposite direction to the wind.
What is force?Force is an external agent acting on an object to change its state of motion or rest or to deform it. There are various kinds of force such as gravitational force, magnetic force, frictional force.
If there are two different forces acting from the same direction will add up together and the net force will be the sum of their magnitudes. If they are in opposite direction, they will balance each other will decreases the displacement.
Hence, the force from the air resistance will balance the force exerted by Jean Paul and his speed will decrease until he apply a greater force forwards.
