If you were designing a lander to work on mars, where on earth would you test it? Why?

emmasim [6.3K]

Hmm good question. Well I would have to test it for where there are no living life. I would have to build another NASA in the County because there is plenty of room there. Mars is made out of Dusty Crust that is about 30 miles thick. And let's say that the desert's Dusty Crust is about 5 miles - 15 miles thick. That will give about the same amount of surface that mars has. So we would know what to build for a perfect lander to work on Mars. This isn't much but it is something.

2. If a train is traveling east at 75 kilometers per hour, what is its velocity?

Vedmedyk [2.9K]

75km/hr due east

Explanation:

The velocity of the train will be 75km/hr due east.

Velocity is given as the rate of change of displacement with time.

Velocity = $\frac{displacement}{time taken}$

Velocity is a vector quantity that has both magnitude and directions.
It is different from speed because it has the directional attribute.
From the given data, we know that the train is moving at 75km per hour. This is the speed of the train.
If we incorporate the direction then we have its velocity.
