A guy named Kirby Had touched only a gear on the projector. Yet there was a out of the blue rip. Kirby did not mind at all and s
solong [7]

The guy named Kirby didn't touch the power button on the projector. If he touched means the projector will work fine.

<u>Explanation</u>:

  • Kirby touched the gear on the projector. He should check the projector carefully before operating the projector. But he didn't check properly.
  • There was a blue rip in the projector. Kirby fails to notice the blue rip. Without minding that he has started the projector. So the tape and the projector is not working well.
  • He should fix the blue rip and he should press the start button in the projector. The mistake is he didn't do that. This is the thing that made the projector ripped.

The disk of radius 0.4 m is originally rotating at ωo=4 rad/sec. If it is subjected to a constant angular acceleration of α=5 ra
Lina20 [59]

Answer:32.4m/s^2

Explanation:

Given data

radius\left ( r\right )=0.4m

Intial angular velocity\left ( \omega_0\right )=4rad/s

angular acceleration\left ( \alpha\right )=5rad/s^2

angular velocity after 1 sec

\omega=\omega_0+\alpha\times\t

\omega=4+5\left ( 1\right )

\omega=9rad/s

Velocity of point on the outer surface of disc\left ( v\right )=\omega_0\timesr

v=9\times0.4 m/s=3.6m/s

Normal component of acceleration\left ( a_c\right )=\frac{v^2}{r}

a_c=\frac{3.6\times3.6}{0.4}=32.4m/s^2

Alina [70]

Answer:

a) ≈ 30 mins

b) 8 vpm

Explanation:

<u>a) Determine how long after the first vehicle arrival will the queue dissipate</u>

The time after the arrival of the first vehicle for the queue to dissipate

= 29.9 mins ≈ 30 mins

<u>b) Determine the average service rate at the parking lot gate </u>

U = A / t

where : A = 240 vehicles , t = 30

U = 240 / 30 = 8 Vpm
