The coefficient of kinetic friction between an object and the surface upon which it is sliding is 0.46. The weight of the object

is 90N. What is the force of friction?

1 answer:

DaniilM [7]2 years ago

4 0

Answer:

the friction force is 41.4N

Explanation:

from f=μ R, where R is the normal reaction. this is equal to the weight of the object

therefore, f = 0.46*90 = 41.4 N

<h2>Movement of Continents</h2>

Explanation:

Alfred Wegener was a German astronomer who proposed the "continental drift" hypothesis in 1910.
Alfred Wegener was not able to explain the movements of the continent in how and in which way they are moved.
He failed in an attempt to explain with the use of tides made the theory undefinable fully.
Also, the major problem with Wegener's theory of Continental Drift was that there was no proper explanation of a mechanism.

Differences between Pressure and upthrust

Angelina_Jolie [31]

Answer:

Pressure is equal to the ratio of thrust to the area in contact. Upthrust is a force exerted by the fluids on an object placed in the fluid . Upthrust acts in upward direction.

Holding onto a tow rope moving parallel to a frictionless ski slope, a 70.1 kg skier is pulled up the slope, which is at an angl

lara [203]

Answer:

given,

mass of the skier = 70.1 Kg

angle with horizontal, θ = 8.6°

magnitude of the force,F = ?

a) Applying newton's second law

$m g sin\theta - F_{rope} = ma$

velocity is constant, a = 0

$m g sin\theta - F_{rope} =0$

$F_{rope} = m g sin\theta$

$F_{rope} = 70.1\times 9.8\times sin 8.6^0$

$F_{rope}= 102.73\ N$

b) now, when acceleration, a = 0.135 m/s²

$F_{rope}-m g sin\theta = ma$

velocity is constant, a = 0.135 m/s₂

$F_{rope} = m g sin\theta+ma$

$F_{rope} = 70.1\times 9.8\times sin 8.6^0+70.1\times 0.135$

$F_{rope}= 112.19\ N$
