Figure 1

Speed is a scalar quantity, It has only magnitude but no direction. It is defined as rate of change of <em>distance</em>.

Mathematically,    speed = distance÷time

                                     S = d ÷ t

                                      S = 2560 ÷ 60

                                      S =  42.67 m/s.

Bits:

Speed is a<em> scalar </em>quantity, that describes only the <em>magnitude (42.67 m/s) </em>of the rate of change of an objects <em>distance. </em>Determine the objects speed requires a unit of <u><em> distance </em></u>per unit of <u><em>time</em></u>

Figure 2

Velocity is a vector quantity, It has both magnitude and direction. It is defined as rate of change of <em>displacement.</em>

<em>Mathematically, Velocity = Displacement </em>÷  time

                                     V =  75 ÷ 1.5

                                     V = 50 Km/h.

Velocity is a <em><u>Vector quantity </u></em>that describes both the<em><u> magnitude</u></em> and <em><u>direction  of </u></em>the rate of change of objects <em><u>displacement </u></em> plus it describes its <u><em>position</em></u>. An objects overall change in position is known as  <em><u>its Displacement  per unit time.</u></em>

Calculate the momentum of a Lion of mass 130-kg and moving at a speed of 22.3 m/s [W]
Sunny_sXe [5.5K]

Answer:

<h2>289.9 kg.m/s</h2>

Explanation:

The momentum of an object can be found by using the formula

momentum = mass × velocity

From the question we have

momentum = 130 × 22.3

We have the final answer as

<h3>289.9 kg.m/s</h3>

Hope this helps you

What is the magnitude and direction (right or left) of the
Sunny_sXe [5.5K]

Answer: 12 N to the right

Explanation:

If we calculate the net force acting on the box, we will have:

<u>In y-component:</u>

Fy_{net}=F_{n}+F_{g} (1)

Where F_{n}=12 N is the Normal force, directed upwards and F_{g}=-12 N is the weight of the box (gravity force), directed downwards.

Fy_{net}=12 N-12 N (2)

Fy_{net}=0 N (3) Hence the net force in the vertical component is zero

<u>In x-component:</u>

Fx_{net}=F_{left}+F_{right} (4)

Where F_{left}=-3 N and F_{right}= 15 N

Fx_{net}=-3 N + 15 N (5)

Fx_{net}=12 N (6) This is the net force in the horizontal component

Therefore, the total net force acting on the box is 12 N directed to the right

How do we know the sun rotate
scoundrel [369]

Answer:

From the movement of sunspots, Galileo discovered that sun rotate s on its own axis.

Explanation:

All the sunspots are traveling across the Sun's head. This movement is part of the Sun's general rotation of its axis. Observations also suggest that the Sun does not rotate like a solid body, but rotates differently because it is a gas. Actually the Sun is spinning faster at its equator than at at its poles. The Sun rotates once every 24 days at its equator, but only once every 35 days at its poles. We learn this by observing the movement of sunspots and other solar features pass through the Sun.
