Perseverance (The Mars rover) drops a sample from 1.8 m above the surface of Mars. If the acceleration due to gravity is 3.721m/s, how long will it take for the sample to
fall and reach Mars's surface?

this isn't the answer but they're the graphs

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
