Robert has just bought a new model rocket, and is trying to measure its flight characteristics. The rocket engine package claims

777dan777 [17]

Answer:

The work done by the drag force is given by 29.96 J

Explanation:

Given :

Thrust force $F = 12.3$ N

Displacement $d = 10.2$ m

Mass of rocket $m = 0.663$ Kg

From work energy theorem,

$W = \Delta K$

$W_{t} - Wd - W_{g} = KE$

Where $W_{t} =$ thrust work $W_{g} =$ gravitational work

$KE = 12.3 \times 10.2 -Wd - 0.663 \times 9.8 \times 10.2$

$KE = 59.2 -Wd$

After cutoff kinetic energy is converted into potential energy,

$KE = Wd' + mg\Delta h$

Put value of KE

$59.2 -Wd = Wd' + 0.663 \times 9.8 \times 4.5$

Work done by drag force is given by,

$Wd'+Wd = 59.2 -29.23$

$= 29.96$ J

Therefore, the work done by the drag force is given by 29.96 J

What is science and why do we study science and what are the benefits we are going to get from it ?

Nina [5.8K]

Answer:

science is define as the study of physics, chemistry, biology, geology and astronomy. science is very important in our daily life.we study science for knowing the knowledge about biological and chemical and many other aspects.without science it is impossible to live our daily life.science is used in each and every steps.

Explanation:

There are many more benefits that we are getting and going to get . Science has already discovered many things ,that we didn't expect efore.And also in progress to discover new things.Science has developed a new type of antivirus that protect us from different virus.Has made different medicine that recover a people. So it is very useful in our life.
