I don't know the net force.cnh1995 said:What is the net force acting on the vehicle?
What do you know about the net force from this?Kajan thana said:The vehicle now accelerates to a constant speed of 55 m s–1.
it is zerocnh1995 said:What do you know about the net force from this?
Yes.Kajan thana said:it is zero
Thank you.cnh1995 said:Yes.
So driving force=resistive force.
Horizontal resistive force, also known as frictional force, is the force that opposes the motion of an object sliding or rolling along a surface. It acts in the opposite direction of the object's motion and is dependent on the surface characteristics and the weight of the object.
Horizontal resistive force can be calculated using the formula F = μN, where F is the resistive force, μ is the coefficient of friction, and N is the normal force (equal to the weight of the object).
The magnitude of horizontal resistive force is affected by the coefficient of friction, the normal force, and the surface characteristics of the object and the surface it is moving on. Other factors such as the speed and temperature can also have an impact.
Horizontal resistive force acts to slow down or stop an object's motion, as it works in the opposite direction of the object's motion. This force can also cause an object to change direction or slide in a different direction.
Horizontal resistive force can be reduced by using lubricants, such as oil or grease, which can decrease the coefficient of friction. It can also be eliminated by using wheels or other mechanisms to reduce the surface area in contact with the surface, thus reducing the normal force and friction.
