This problem uses the same concepts as Multiple-Concept, except that kinetic, rather than static, friction is involved. A crate

is sliding down a ramp that is inclined at an angle 30.6 ° above the horizontal.
The coefficient of kinetic friction between the crate and the ramp is 0.360. Find the acceleration of the moving crate.

Answer:

1.96 m/s^2

Explanation:

angle of inclination, θ = 30.6°

coefficient of friction, μ = 0.36

Acceleration of the crate

a = g Sin θ - μ g Cos θ

a = 9.8 ( Sin 30.6 - 0.36 x Cos 30.6)

a = 9.8 ( 0.509 - 0.309)

a = 1.96 m/s^2

Thus, the acceleration f the crate is 1.96 m/s^2.

What factors do NOT affect friction between two objects? Explain how you know this.
Black_prince [1.1K]

The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces

(ii) roughness of the surface

(iii) deformation of bodies.

A tight knot can be easily opened by using a long spanner. Give reason.
olga nikolaevna [1]

Answer:

Torque

Explanation:

loosening loosening a boat requires a certain amount of torque which is the product of the force acting on the wrench and the moment arm, or distance from the center of rotation at which the force is applied. the longer the handle, the last force it takes to generate the same amount of torque
