A high school physics student claims her muscle car can achieve a constant acceleration of 10 ft/s/s. Her friend develops an acc
Nikolay [14]

Answer: Ф = 17.2657 ≈ 17°

Explanation:

we simply apply ET =0 about the ending of the rod

so In.g.L/2sinФ - In.a.L/2cosФ = 0

g.sinФ - a.cosФ = 0

g.sinФ = a.cosФ

∴ tanФ = a/g

Ф =  tan⁻¹ a / g

Ф = tan⁻¹ ( 10 / 32.17405)

Ф = tan⁻¹ 0.31080948777

Ф = 17.2657 ≈ 17°

Therefore the angle of rotation of the rod during this acceleration is 17.2657 ≈ 17°

vivado [14]

Answer:

10 159.8744 m

Explanation:

Hi there!

Since

<em>   1 mile = 1609.34 m</em>

and:

<em>   1 yard = 0.9144 m</em>

We have that:

  <em>6 miles + 551 yards = 6 *(1609.34) + 551*(0.9144) m</em>

Therefore, the distance is (in meters):

 d = 10 159.8744 m

Rounded to the first decimal

 d = 10 159.9 m
