<h2>Answer</h2>

1 V = 1 kg m2 s−² C

1 V = 1 kg m2 s−³ A−1

(one kilogram meter squared per second cubed per ampere)

<h2>Explanation</h2>

<em>The work required to move an electric charge of one coulomb through an electrical potential difference of one volt,</em>

<h2> Volts = Joules / Coulombs</h2><h2 />

    Joules = Newton x metre

     Volts = Nm / coulombs

    Newton = kg x metre / second ²

    Volts = kg x metre / second ² coulombs

Volt in terms of meters (m), seconds (s), kilograms (kg), and coulombs (c)

<h3>For further:</h3>

Coulomb = Amp * second

Volts = kg x metre / second ³ Amp

<h2 />

A bicyclist in the Tour de France crests a mountain pass as he moves at 18 km/h. At the bottom, 4.0 km farther, his speed is at
Allisa [31]

We are given:

v0 = initial velocity = 18 km/h

d = distance = 4 km

v = final velocity = 75 km/h

a =?

<span>
We can solve this problem by using the formula:</span>

v^2 = v0^2 + 2 a d

 

75^2 = 18^2 + 2 (a) * 4

5625 = 324 + 8a

<span>a = 662.625 km/h^2</span>

Arocket launches at an angle of 33.6 degrees from the horizontal at a
babymother [125]

Answer:

Y component = 32.37

Explanation:

Given:

Angle of projection of the rocket is, \theta=33.6

Initial velocity of the rocket is, u=58.5

A vector at an angle \theta with the horizontal can be resolved into mutually perpendicular components; one along the horizontal direction and the other along the vertical direction.

If a vector 'A' makes angle \theta with the horizontal, then the horizontal and vertical components are given as:

A_x=A\cos \theta(\textrm{Horizontal or X component})\\A_y=A\sin \theta(\textrm{Vertical or Y component})

Here, as the velocity is a vector quantity and makes an angle of 33.6 with the horizontal, its Y component is given as:

u_y=u\sin \theta

Plug in the given values and solve for u_y. This gives,

u_y=(58.5)(\sin 33.6)\\u_y=58.5\times 0.55339\\u_y=32.373\approx32.37(\textrm{Rounded to two decimal places})

Therefore, the Y component of initial velocity is 32.37.
