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!

*URGENT* Why is understanding motion so important? Be sure to explain in your own words.
levacccp [35]

Answer:

Motion is one of the important issues of Physics. We know that if we are not moving but still earth is moving. Motion is a bit of the machinist's Department of Physics. Several laws are provided for explaining the theory of motion and evolution in motion. The motion and transformation are defined in terms of strength which is wanted for creating an object in a motion state.

PLEASE ANSWER, 75 PTS, AND BRANLIEST!
n200080 [17]

Answer:

An electromagnet is a device which moving electric charges(current) in a coil of wire create a magnet. Electromagnets can easily be turned off and on because it is a electromagnet. When current flows through a wire, a magnetic field is produced around a wire and create an electromagnet. The coils are always made of copper wire because copper is a good conductor of electricity.
