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,
\(t=200\times24\)
\(t=4800\)
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,
\(s=\dfrac{d}{t}\)
Using the above formula calculate the value of the speed of the spacecraft.
\(s=\dfrac{192000000}{4800}\)
\(s=40000\)
Hence, the value of the speed of the spacecraft is 40000 km per hour.
