A force of 2000N pulls a load at angle of 60 degrees with the horizontal. calculate the coefficient of static friction

LenKa [72]

Answer:

√3

Step-by-step explanation:

From the formula used in calculating Friction, we have:

Frictional Force = coefficient of Friction × Reaction

i.e Fr = μ × R

Resolving Frictional Force and Reaction of a body moving with on an Inclined plane,

Frictional Force = mass × g × sin a

where a = to the angle given

Reaction = mass × g × cos a

Therefore,

mass × g × sin a = μ × mass × g × cos a

mass and g cancels out on both sides.

Therefore,

sin a = μ × cos a

make "μ" subject.

μ = sin a/cos a

(recall: tan a = sin a /cos a)

μ = tan a

recall a = angle given = 60°

μ = tan 60°

μ = √3

or simply recall that

μ = tan a

μ = tan 60°

μ = √3

the equation d =40 - 1/5 m how many miles does anthony have to finish the race if he has been riding for one hour and twenty min

Levart [38]

Question:

Anthony is riding in a race.The equation d=40-1/5m, where d= distance in miles and m= minutes,can be used to estimate the number of miles anthony has left before reaching the finish line.how many miles does anthony have to finish the race if he has been riding for one hour and twenty minutes?

Answer:

Antony has to ride for 24 miles

Solution:

Given that,

The equation used to estimate the number of miles is:

$d = 40-\frac{1}{5}m$

Where, "m" is the minutes and "d" is the distance

Given that Antony is riding for 1 hour 20 minutes

We know that,

1 hour = 60 minutes

1 hour 20 minutes = 60 minutes + 20 minutes = 80 minutes

Substitute m = 80 in given eqn

$d = 40 - \frac{1}{5} \times 80\\\\d = 40 - 16\\\\d = 24$

Thus Antony has to ride for 24 miles
