A descent vehicle landing on Mars has a vertical velocity toward the surface of Mars of 5.5 m/s. At the same time, it has a horizontal velocity of 3.5 m/s.

a. At what speed does the vehicle move along its descent path?

b. At what angle with the vertical is this path?

Explanations of the steps and the process is what im looking for, Thank you very much for any help!

From what I understand, for part a it wants the magnitude of the resulting velocity in both directions. Part b will be the angle between it's path of travel with the y-axis. I would sketch the info to get a better idea.
