What is the Rover's landing speed? (Picture)
1 Answer
Explanation:
Total energy remains the same during this motion,as motion is only due to the effect of gravity.
So,total energy on top of crater was
While landing it will have purely kinetic energy,so at that time if velocity is
So,
Solving we get,
ALTERNATIVELY
The Mars rover will follow a parabolic path in its journey from the
Suppose,while landing it will have vertical component of velocity
So,
Now,horizontal component of velocity remains the same i.e
So,landing velocity =
