A woman walks into a carpet store wearing high-heeled shoes with a circular heel of diameter 0.987 cm. To the dismay of the stor

e manager, she balances on one heel on an expensive carpet sample. If she has a mass of 53.0 kg, determine the pressure she exerts on the carpet sample.

To solve this problem it is necessary to apply the concepts related to the Pressure which describes the amount of Force made on an area unit.

Its mathematical expression can be defined as

P = \frac{F}{A}

Where,

F= Force

A = Area

Our values are given as

d = 0.987*10^{-2}m

With the diameter we can find the Area of the circular heel, that is

A = \pi (\frac{0.987*10^{-2}}{2})^2

A = 7.6511*10^{-5}m^2

To find the force by weight we need to apply the Newton's second Law

F = mg

F = 53*9.8

F = 519.4N

Finally the pressure would be

P = \frac{F}{A}

P = \frac{519.4}{7.6511*10^{-5}}

P = 6788566.35Pa

P = 6.788MPa

Therefore the pressure that she exerts on the carpet sample is 6.788Mpa

BALANCED FORCES

When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . a stationary object stays still. ... a moving object continues to move at the same speed and in the same direction.

how do you find work when only given the angle a sled is pulled, the mass, the coefficent of kinetic friction and distance
Sergio039 [100]

Answer:

W = F * s    

Work done equals applied force * distance traveled

Apparent weight = M g (1 - sin θ)     since some of applied force will lighten sled

μ = coefficient of kinetic friction

F cos θ = force applied to motion of sled

s = distance traveled

[μ M g (1 - sin θ)] cos θ * s = work done in moving sled

Note that F = μ M g    if applied force is in the horizontal direction
