After the torque has been applied for 0.3 s, what are the magnitude and direction of the angular momentum about the center of the disk?

Answers

Answer 1

The magnitude and direction of the angular momentum about the center of the disk is 0.996 kgm²/s.

Angular acceleration of the disk

The angular acceleration of the disk is determined by applying the principle of conservation of angular momentum as shown below;

Fr = Iα

α = Fr/I

Where;

I is the moment of inertia of the solid disk

I = ¹/₂MR²

I = ¹/₂ x (0.5) x (0.08)²

I = 1.6 x 10⁻³ kgm²

[tex]\alpha = \frac{14 \times 0.22}{1.6\times 10^{-3}}\\\\\alpha = 1,925 \ rad/s^2[/tex]

Final angular velocity of the disk

ωf = ωi + αt

ωf = 45 + (1925 x 0.3)

ωf = 622.5 rad/s

Angular momentum

L = Iω

L = (1.6 x 10⁻³) x (622.5)

L = 0.996 kgm²/s

Thus, the magnitude and direction of the angular momentum about the center of the disk is 0.996 kgm²/s.

The complete question is below:

A uniform solid disk with radius 8 cm has mass 0.5 kg (moment of inertia I = (1/2)MR²). A constant force 14 N is applied as shown. At the instant shown, the amount of string that has wound off the disk is d = 22 cm, and the angular velocity of the disk is 45 radians/s into the page.

An ellipse is represented by the equation . each directrix of this ellipse is a ________________________ from the center on the major axis.

Answers

The true statement about the directrix is that each directrix of this ellipse is 31.25 units from the center on the major axis.

How to determine the distance of the directrix?

The equation of the ellipse is given as:

[tex]\frac{(x - 5)^2}{625} -\frac{(y - 4)^2}{225} =1[/tex]

The above means that:

a^2 = 625

a = 25

b^2 = 225

b = 15

Calculate c using:

c^2 = a^2 - b^2

This gives

c^2 = 625 - 225

Evaluate the difference

c^2 = 400

Evaluate the square root

c = 20

The equation of the directrix is

x - x₀ = ± a²/c

So, we have:

x - x₀ = ± 625/20

Evaluate the quotient

x - x₀ = ± 31.25

This means that, each directrix is 31.25 units from the center on the major axis.
