An airplane is flying in a horizontal circle at a speed of 100 m/s. The 80.0 kg pilot does not want the centripetal acceleration
Tema [17]

Answer:

The force will be "5,488". A further solution is provided below.

Explanation:

The given values are:

speed,

v = 100m/s

mass,

m = 80 kg

acceleration,

a = 7

Now,

Radius will be:

⇒ r=\frac{v^2}{ac}

⇒    =\frac{(100)^2}{7\times 9.8}

⇒    =\frac{10000}{68.6}

⇒    =145.77

Force will be:

⇒ F=m\times ac

⇒     =80\times 68.6

⇒     =5488

PLEASE HELP ASAP.

Volume of the original block (V) of length (l), width (w) and height (h) is given by the following equation

V = l*b*h

hence volume of original block, V =  (6)(4)(10) = 240 cm^{3}

Now say we cut this block in two equal parts, than the length of new block will    be 6/2 = 3 cm ; where as its width and height will be same as of original block i.e. 4 cm and 10 cm respectively.

So, Volume of half-block is = (3)(4)(10) = 120 cm^{3} ; or we can say that the volume of half-block is half that of orignal block.

For the winter, a duck flies 10.0 m/s due south against a gust of wind with a velocity of 2.5 m/s. What is the resultant velocit
maria [59]

Answer:

c. 7.5 m/s south

Explanation:

<u>Given the following data;</u>

Velocity of duck = 10m/s due South

Velocity of wind = 2.5m/s

To find the resultant velocity;

Since we know that the duck is flying against a gust of wind, we would have to subtract the velocity of the gust of wind from that of the duck.

This ultimately implies that, the gust of wind (headwind) would decrease the resulting velocity of the duck because it approaches the duck from the front.

Resultant velocity, /V/ = 10 - 2.5

Resultant velocity, /V/ = 7.5m/s South.

<em>Therefore, the resultant velocity of the duck is 7.5m/s south. </em>

A box is being pulled to the right on flat ground with a force of 112 N at an angle of 42° to the horizontal. What is the x-comp
sasho [114]
The x-component is related with the Force through the trigonometric function cosine.

cos(42°) = x-component / F ⇒ x-component = Fcos(42°) = 112N*0.743 = 83.2 N
