7 0

Answer:

22m/s

Explanation:

Step one:

Given data

Initial velocity of roller coster u= 6 m/s

Final velocity v= 72m/s

time t= 3 seconds

Required

We want to solve for the acceleration of the roller coster

Step two:

From the formula

acceleration= v-u/t

substitute

a= 72-6/3

a=66 /3

a= 22 m/s

The cars acceleration 22m/s

In a carnival booth, you can win a stuffed giraffe if you toss a quarter into a small dish. the dish is on a shelf above the poi
Georgia [21]

components of the speed of the coin is given as

v_x = v cos60

v_x = 6.4 cos60 = 3.2 m/s

v_y = vsin60

v_y = 6.4 sin60 = 5.54 m/s

now the time taken by the coin to reach the plate is given by

t = \frac{\delta x}{v_x}

t = \frac{2.1}{3.2}

t = 0.656 s

now in order to find the height

h = vy * t + \frac{1}{2} at^2

h = 5.54 * 0.656 - \frac{1}{2}*9.8*(0.656)^2

h = 1.52 m

so it is placed at 1.52 m height

Match the scenario to the type of potential energy represented.
Phantasy [73]

Explanation:

A battery sits in an iPod before the iPod is turned on      Chemical

A man at a carnival lifts a hammer high over his head

before swinging it down onto a pad.                                 Gravitational

A positively charged particle is slowly moved away

from a strong, negatively charged plate                               Electric

The string of a bow and arrow is pulled tight.                      Elastic

Energy is defined as the ability to do work. There are two main forms of energy which are:

  • Potential energy
  • Kinetic energy

Chemical energy energy is a form of potential energy produced through chemical reactions. A car battery is an electrochemical that converts chemical energy into electrical energy for use in the iPod. The battery is made up of electrodes through which electron flows in one direction and current is generated by the potential difference set up

Gravitational energy is a form of potential energy that tends to pull all bodies to the center of the earth. It is an attractive force.

Electrical energy is a form of energy produced through the flow of electric current in a body. As the positive charge moves away from the strong negative plate, an electric current is produced.

Elastic energy is a potential energy stored in elastic bodies that can be stretched and are not plastic.

Two particles are located on the x axis. particle 1 has a mass m and is at the origin. particle 2 has a mass 2m and is at x = +l
wlad13 [49]

The solution would be like this for this specific problem:

<span>
The force on m is:</span>

<span>
GMm / x^2 + Gm(2m) / L^2 = 2[Gm (2m) / L^2] -> 1

The force on 2m is:</span>

<span>
GM(2m) / (L - x)^2 + Gm(2m) / L^2 = 2[Gm (2m) / L^2] -> 2

From (1), you’ll get M = 2mx^2 / L^2 and from (2) you get M = m(L - x)^2 / L^2 

Since the Ms are the same, then 

2mx^2 / L^2 = m(L - x)^2 / L^2 

2x^2 = (L - x)^2 

xsqrt2 = L - x 

x(1 + sqrt2) = L 

x = L / (sqrt2 + 1) From here, we rationalize. 

x = L(sqrt2 - 1) / (sqrt2 + 1)(sqrt2 - 1) 

x = L(sqrt2 - 1) / (2 - 1) 


x = L(sqrt2 - 1) </span>

 

= 0.414L

 

<span>Therefore, the third particle should be located the 0.414L x axis so that the magnitude of the gravitational force on both particle 1 and particle 2 doubles.</span>
