Respuesta :
The force applied by the cyclist to maintain a constant velocity is 23.5N.
Given data,
The mass of the cyclist and her bicycle is: m=70kg
The frictional force acting against the motion of the bicycle is:
f=−23.5N
The expression for the force applies by the cyclist is,
F + f=ma
Here, a is the acceleration of the cyclist.
As the cyclist moves with the constant velocity so, its acceleration is zero.
Substitute the given values in the above expression.
F−23.5N=70kg (0)
F=23.5N
Thus, the force applied by the cyclist to maintain a constant velocity is 23.5N
What is the formal name of the law of force and acceleration?
The Law of Force and Acceleration, often known as Newton's Second Law of Motion, states that an object accelerates when it is subjected to a force using the equation net force = mass x acceleration. As a result, the object's acceleration is inversely proportional to its mass and directly related to its force.
What is an object's acceleration?
An object is considered to exert a force when it accelerates through space because acceleration is the rate at which an item's speed changes. The second law of motion of Newton explains this concept.
