A mouse runs along a baseboard in your house. The mouse's position as a function of time is given by x(t)=pt2+qt, with p = 0. 40

Gelneren [198K]

The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s

<h3>Velocity function </h3>

Given the equation for the position of the mouse expressed as:

$x(t)=pt^2+qt\\$

The velocity of the particle is expressed as:

$v(t)=2pt+q$

Given that p = 0. 40 m/s and q = -1. 10 m/s, the equation will become:

$v(t)=2(0.4)t-1.10\\v(t)=0.8t - 1.10$

If the time is t = 1.0 s, the velocity will be:

$v(1) = 0.8 - 1.10\\v(1) = -0.3m/s$

Similarly if t = 4.0ssec, hence:

$v(4) = 3.2 - 1.10\\v(4) = 2.1m/s$

The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s

Write about people of AAD, SAMUD and PHAROH

Luden [163]

The people of Aad were an ancient tribe of Saudi Arabia. Their city was known as Iram. The tribe was popular for its cleverness and physical strength and therefore, they are also called giants. They were so strong and intelligent that they could carve mountains and use it as their homes. , the Thamūd were the successors of a previous nation called the ʿĀd, who had also been destroyed for their sins. They lived in houses carved into the surface of the earth. God chose the prophet Ṣāliḥ to warn the polytheistic Thamūd that they should worship the One God.
