The rocket should be fired for <u>129600 seconds.</u>

Why?

We can calculate for how long should the rocket be fired by using the following equation:

Force=mass*aacceleration=mass*\frac{v-v_{o}}{time} \\\\time=\frac{mass*(v-v_{o})}{Force}

From the statement we know:

- Initial speed equal to zero.

- Force equal to 272N.

- Final speed (for the moment) equal to 62 m/s.

- Mass equal to 72000 Kg.

So, substituting and calculating, we have:

time=\frac{mass*(v-v_{o})}{Force}

time=\frac{mass*(v-v_{o})}{Force}\\\\time=\frac{72000*(63\frac{m}{s} -0)}{35\frac{Kg.m}{s^{2}}}=129600s

Hence, we have:

Variables: Time

Equations:

Force=mass*aacceleration=mass*\frac{v-v_{o}}{time} \\\\time=\frac{mass*(v-v_{o})}{Force}

Answers: The rocket should be fired for 129600 seconds.

Have a nice day!

magnitude of velocity does not change but the direction changes. Can we say that it is an accelerated motion?
Olenka [21]

Answer:

MRCORRECT has answered the question

Explanation:

Since velocity is a vector, it can change either in magnitude or in direction. Acceleration is therefore a change in either speed ordirection, or both. Keep in mind that althoughacceleration is in the direction of the changein velocity, it is not always in the direction ofmotion.

A 2.0-kg ball has a momentum of 25kg.m/s what is the ball's speed?
Reil [10]

We know, momentum = mass * speed

25kgm/s = 2 kg * s

s = 25/2 = 12.5 m/s

a blackbody is radiating with a characteristic wavelength of 9 microns what is the blackbody temperature answer in kelvin
Daniel [21]

This question involves the concepts of Wein's displacement law and characteristic wavelength.

The blackbody temperature will be "3.22 x 10⁵ k".

<h3>WEIN'S DISPLACEMENT LAW</h3>

According to Wein's displacement law,

\lambda_{max} T = c\\\\T=\frac{c}{\lambda_{max}}

where,

  • \lambda_{max} = characteristic wavelength = 9 μm = 9 x 10⁻⁹ m
  • T = temperature = ?
  • c = Wein's displacment constant = 2.897 x 10⁻³ m.k

Therefore,

T=\frac{2.897\ x\ 10^{-3}\ m.k}{9\ x\ 10^{-9}\ m}

T = 3.22 x 10⁵ k
