What is the maximum speed with which a 2500 kg car can round a turn of radius 60 m on a level road if the coefficient of static friction between tire and road is 7?
Really? A coefficient of friction of 7? Unheard of. Probably 0.7 Use F = mv^2 / r where F will be the centripetal force as well as the frictional force, (mu)mg. Solve for v.
Physics coefficient of friction radius of 60 m is properly banked for a car traveling 60 kmh what must be the coefficient of static friction for a car not to skid when travelling at?
Badly phrased, not enough information
If you know the coefficient of friction how do you find the maximum velocity to maintain a circular path at a given radius?
say mass(m) = 10 kg, radius(r) = 10 m, say friction coefficient = 0.5 force to break friction = 10 * 0.5 = 5 kgf = say 50 n to find acceleration required to produce this force use f=m*a, shuffle to a = f / m so a = 50 / 10 = 5 (m/s)/s, install in a = v^2 / r, so 5 = v^2 / 10, so 10 * 5 = v^2, so sq. root 50 = v, so v = 7.07 metres / second if friction coefficient and radius remain the same, altering the mass wont alter the velocity at breakaway point
A 200-kg car rounds a circular turn of radius 20 m If the road is flat and the coefficient of the friction between tires and road is 70 how fast can the car go without skidding?
define skidding.... 30mph.
What is the maximum speed with which a 1200-kg kg car can round a turn of radius 93.0m on a flat road if the coefficient of static friction between tires and road is 0.45?
The idea here is to: * Write an equation for the centripetal acceleration, using v squared / r. * Calculate the corresponding centripetal force, using Newton's Second Law (multiply the previous point by the mass). * Write an equation for the force of friction. * Equate the two forces, and solve.
What is the maximum speed with which a 1200-kg car can round a turn of radius 80.0 rm m on a flat road if the coefficient of friction between tires and road is 0.65?
Friction = m Cf g centripetal force = mv^2/r maxium speed Ff = Fc mCfg = mv^2/r v=sqrt (Cf g r) v = sqrt (.65 *9.81 *80m) v = 22.58 m/s
What is the maximum speed with which a 1130 kg car can round a turn of radius 60 m on a flat road if the coefficient of friction between tires and road is 0.80?
m=1130kg r=60 m Friction coefficient= 0.80 Formula: v=(F*r/m)^1/2 where F is the normal force, r is the radius, and m is the mass. The equation is to the 1/2 power because the answer needs to be square rooted. In order to solve this equation, you need to calculate F which =mg (mass times value of gravity). The value of gravity is 9.80m/s F=1130kg*9.80m/s=11074 Newtons The value of F is now multiplied by the friction coefficient to determine the maximum friction force: Fmax=11074*.8=8859. 8859 is the value of FN that we can now plug into our equation below. so now we can solve the equation: v=((8859*60/1130))^1/2 v=21.68 meters/second or about 22 m/s This means that the car can travel as fast as about 22 meters/ second and stay on the curve without sliding off.
How long does it take for a solid to rest in a settling basin?
In theory - forever. In practice it will depend on many factors: friction coefficient, mass of object, radius of basin, initial conditions.
How do you calculate the roughness coefficient of a river?
The roughness coefficient of a river, also known as Manning's roughness coefficient, is typically determined through field measurements or reference tables based on the type of channel bed and vegetation present in the river. It is used in the Manning's equation to estimate the flow velocity in open channels. Collecting data on the slope, cross-sectional area, and flow rate of the river, and then using the Manning's equation, can help determine the roughness coefficient.
What is the r in mathematics?
The answer depends on the context. In geometry it is usually the radius, in statistics it is the regression coefficient.
