To find the coefficient of static friction, you can use the formula µ = v^2/rg, where µ is the coefficient of static friction, v is the velocity, r is the radius, and g is the acceleration due to gravity. This formula assumes that the object is moving in a circular path with a constant speed. 2. Can I use any unit for velocity and radius when ...
To calculate displacement, you will need to use the formula: displacement = (mass * velocity^2) / (2 * coefficient of friction). This formula takes into account the mass of the object, its velocity, and the coefficient of friction, which represents the resistance to motion. 2.
To determine the acceleration of the car, you can use the equation Vf^2=Vo^2 +2aΔx and calculate the acceleration to be -7.53 m/s^2. To determine the coefficient of friction between the tires and the road, you can use the equation Ff=μmg and set it equal to Ff=ma. By canceling out the mass and solving for μ, you can.

1. What is the formula for finding velocity with given information? The formula for finding velocity (v2) with given coefficient of friction (µ), distance (d), mass (m), and initial velocity (v1) is v2 = v1 + √ (2µgd/m), where g is the acceleration due to gravity (9.8 m/s²). 2.
In summary, the problem involves finding the coefficient of friction between a ladder leaning against a wall at angle θ and the floor, with the ladder being L meters long and having a mass of m. The problem assumes that there is no friction at the top of the ladder. The equations used to solve this problem include ΣFx = 0, ΣFy = 0, and Στ ...
The coefficient of friction can be calculated by dividing the force required to move an object by the normal force, which is the force pushing the two surfaces together. This can be represented by the equation: coefficient of friction = force/normal force. 3.
To find the minimum coefficient of friction, we can use the formula Ff = μN, where Ff is the force of friction, μ is the coefficient of friction, and N is the normal force. In this case, the normal force is equal to the force needed to keep the child in the circular path, which we found to be 223.976445 N in part 2.
Homework Statement A force, F, applied to a 12.1 kg crate at an angle (theta) of 41.0 degrees makes the crate move horizontally with a constant acceleration of 1.85 m/s^2. The coefficient of kinetic friction between the crate and the surface is uk=0.35. Calculate the magnitude of F...
The formula for solving for distance using only initial velocity and coefficient of friction is: d = (vi)2 / 2μg, where d is the distance, vi is the initial velocity, μ is the coefficient of friction, and g is the acceleration due to gravity. 2. How do you determine the coefficient of friction for a given surface?
The coefficient of friction on a banked curve can be calculated using the formula: μ = tanθ, where μ is the coefficient of friction and θ is the angle of the banked curve. This formula assumes that the vehicle is moving at a constant speed and does not rely on the mass or weight of the vehicle. 3.
