Respuesta :
Speed is the rate of change of position of a particle or an object with respect to the time. It can also describes as the rate of which a particle or object moves.The value of the speed of the spacecraft is 40000 km per hour.
Given-
The distance between Earth and Mars is 192,000,000 km.
Time taken by the spacecraft to send a space buggy from earth to mars is 200 days.
Time taken in hours t,
[tex]t=200\times24[/tex]
[tex]t=4800[/tex]
The speed of the spacecraft has to be calculate. For this we need to know about the speed.
What is speed?
Speed is the rate of change of position of a particle or an object with respect to the time. It can also describes as the rate of which a particle or object moves.
The speed can be calculate by the calculating the ratio of the distance traveled d to the time taken t.
Mathematically,
[tex]s=\dfrac{d}{t}[/tex]
Using the above formula calculate the value of the speed of the spacecraft.
[tex]s=\dfrac{192000000}{4800}[/tex]
[tex]s=40000[/tex]
Hence, the value of the speed of the spacecraft is 40000 km per hour.
