What is the greatest acceleration a runner can muster if the friction between her shoes and the pavement is 72 percent of her weight?
The greatest acceleration a runner can achieve is 0.28 times the acceleration due to gravity (0.28g), where g is 9.81 m/s^2. This is because the frictional force is equivalent to 0.72 times the runner's weight, which opposes the force of the runner's push-off.
What is the greatest acceleration that can be generated by a runnerif the coefficent static friction between shoes nd road is 0.95?
The greatest acceleration a runner can generate is limited by the static friction force, which is given by the product of the coefficient of static friction and the normal force. If the coefficient of static friction is 0.95, then the maximum acceleration would be 0.95 times the acceleration due to gravity (9.81 m/s^2), which equals 9.31 m/s^2.
What force is responsible for the painful difference between sliding on pavement and sliding on grass?
friction: the force that resists relative motion between two bodies in contact.
Wet pavement is more slippery than dry pavement because of force needed to overcome what friction is less than the force needed to overcome sliding friction?
On wet pavement, the presence of water reduces the friction between the tires and the road surface, making it more slippery. This is because the force needed to overcome static friction (needed to start moving) is less than the force needed to overcome sliding friction (needed to maintain motion). As a result, it is easier for a vehicle to slide or skid on wet pavement compared to dry pavement.
What force is responsible for the painful difference between sliding on grass and sliding on pavement?
The force responsible for the painful difference between sliding on grass and sliding on pavement is primarily friction. Grass has more resistance and provides a softer landing surface, reducing the impact force compared to the harder and more abrasive surface of pavement. This difference in friction and surface roughness affects how energy is dissipated during a slide, leading to a less painful experience on grass compared to pavement.

Why is dry pavement creates more friction than ice pavement does?
Dry pavement creates more friction than ice pavement because when surfaces are dry, there is more contact between the tires and the road, leading to increased friction. On the other hand, ice has a low coefficient of friction, causing tires to slip more easily since there is less traction between the ice and the tires.
What force is responsible for the painful difference between sliding on pavement and sliding on grass?
friction: the force that resists relative motion between two bodies in contact.
Why does it take longer for cars to stop on pavement covered in ice then pavement that is dry?
WHY!It is because the ice makes the friction between the tires and the pavementgreater.

Why is friction impotant when you walk?
If there were no friction between your soles and the pavement, you would be unable to apply the force needed to walk forwards. Think how difficult it is to walk on ice where the friction is low.

When and how does friction affect the acceleration of a balloon racer?
Friction affects the acceleration of a balloon racer by creating a force that opposes the motion of the racer. Higher friction between the racer's wheels and the surface will result in a lower acceleration, as more energy is needed to overcome this resistance. Reducing friction by using smoother wheels or lubricants can improve the acceleration of the balloon racer.
What is the relation between friction force and acceleration?
The friction force acting on an object is directly proportional to the object's acceleration. As acceleration increases, the friction force opposing the motion of the object also increases. This relationship is described by the equation F_friction = μ * N, where μ is the coefficient of friction and N is the normal force acting on the object.
Is the friction between car tires and pavement greater when the car is at rest or in motion?
Interesting - static friction is greater than moving friction; but if the car is not in a skid, then the part of the tires in contact with the road is not moving ... thus static friction holds in both cases.
The friction between a book at rest and the desk it is lying on is an example of what?
This is the example of Newton third law and law of inertia.
