A particle moving along the x-axis has a position given by x = (24t – 2.0t 3 ) m, where t is measured in s. What is the magnitud
Vitek1552 [10]
<h2>The magnitude 24 (\dfrac{m}{s^2} ) of the acceleration of the particle when the particle is not moving.</h2>

Explanation:

Given,

A particle moving along the x-axis has a position given by

x=(24t-2.0t^3) m      ........ (1)

To find, the magnitude (\dfrac{m}{s^2} ) of the acceleration of the particle when the particle is not moving = ?

Differentiating equation (1) w.r.t, 't', we get

\dfrac{dx}{dt} =\dfrac{d((24t-2.0t^3))}{dt}

⇒ \dfrac{dx}{dt} =24(1)-3(2.0)t^{2} =24-6t^{2}     ....... (2)

⇒ 24-6t^{2} = 0

⇒ t^{2}=2^{2}

⇒ t = 2 s

Again, differentiating equation (2) w.r.t, 't', we get

\dfrac{d^2x}{dt^2} =-12t

Put t = 2, we get

\dfrac{d^2x}{dt^2} =-12(2)=24

Thus, the magnitude 24 (\dfrac{m}{s^2} ) of the acceleration of the particle when the particle is not moving.

A student walks the hallway for 25 m stops to talk and continues down the hallway another 10 m what is the distance and displace
brilliants [131]

Answer:

Distance = displacement = 35m

Explanation:

The distance of the student is how far he has gone.

Distance = 25m + 10m

Distance = 35m

Displacement is the distance specified in specific direction. Since the student walk in the sane direction, thence the displacement is also 35m

What is the change all living things undergo as the grow
Vladimir [108]
All of the change that living things undergo as they grow is called development. That is the name when the changes are within a single unit and over a period of time as short as a lifetime. When the change occurs over thousands of years then it's called evolution.
