by vector addition.

< 5 m, 270 degrees> + < 8 cm, 90 degrees>

=< 500 cos 270, 500 sin 270 > + < 8 cos 90, 8 sin 90 >

=< 0, −500 > + < 0, −8 >

=< 0, −492 > cm

The so-called parallelogram law lays forth the guidelines for adding two or more vectors together. By aligning the two vectors A and B head to tail and drawing the vector from the free tail to the free head, the vector sum A+B is created. If A=(a 1,a 2,...,a n) and B=(b 1,b 2,...,b n), then vector addition can be done in Cartesian coordinates by adding the respective components of the vectors.

A+B=(a 1+b 1,a 2+b 2,...,a n+b n).

The Wolfram Language uses a plus symbol to denote vector addition, as in a1, a2,..., an+b1, b2,..., bn

An airplane flies in a loop (a circular path in a vertical plane) of radius 160 m . The pilot's head always points toward the ce
notka56 [123]

Answer:

a) 39.6 m/s b) 4123 N

Explanation:

a) At the top of the loop, all of the forces point downwards (force of gravity and normal force).

Fnet=ma

ma=m(v^2/R) (centripetal acceleration)

mg=m(v^2/R)

m cancels out (this is why pilot feels weightless) so,

g=(v^2/R)

9.8 m/s^2 = v^2/160 m

v^2=1568 m^2/s^2

v=39.6 m/s

b) At the bottom of the loop, the normal force and the force of gravity point in opposite directions. The normal force is the weight felt.

Convert 300 km/hr to m/s

300 km/hr=83.3 m/s

Convert pilot's weight into mass:

760 N = 77.55 kg

Fnet=ma

n-mg=m(v^2/R)

n=(77.55 kg)(((83.3 m/s)^2)/160 m)+(77.55 kg)(9.8 m/s^2)

n=3363.2 N+760 N=4123 N

Data charts would use descriptive statistics to show accurate reading measured throughout the lab. Charts and graphs can also be used to show the progress and result of the lab.

What are two ways you can increase power by climbing the stairs?
Nina [5.8K]

Answer:

change the

  • time
  • distance
  • force.

Explanation:

P = W/time

W = F*d

You have control over how fast you go up the stairs.

You also have control over how far up the stairs you go.

Therefore the answer is

  • time
  • distance

If you don't like distance as an answer, you can carry something up the stairs -- anything that increases F will do.

a spring has a force constant of 100 n/m and an unstretched length of 0.07 m. one end is attached to a post that is free to rota
Digiron [165]

F equals 3N with respect to the circle's center, moving in the same direction as the centripetal acceleration.

<h3>How much centripetal force is there in a centrifuge?</h3>

Centripetal force is the force that pushes an item in the direction of its center of curvature. It is fundamental to how a centrifuge operates.

<h3>On a roller coaster, what is centripetal force?</h3>

An item travelling in a circle is pushed inward toward what is known as the center of rotation, which is essentially what a roller coaster accomplishes when it travels through a loop. The force that maintains an object moving along a curved route is this pull toward the center, or centripetal force.
