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

a. At what speed does the vehicle move along its descent path?
b. At what angle with the verticle is this path?

Please help me.
I don't understand how to figure this problem out.

Show each step you used. I don't understand how this problem works. Please do not use the pythagorean theorem, use trig functions instead.

It seems like I always hear that "there couldn't have been life on "X" planet because there was never water. But it seems to me that is only life as WE know it. I just feel like yes you are not going to have a human like organism without the presence of water, but why not some other type of oraganism that somehow has spawned based on the perfect elemental availability on another planet. I dunno I'm just talking. Any thoughts?

the reaction system: CS2 (g) +4H2 (g) yields CH4 (g) +2H2S(g) is at equilibrium. What would describe the behavior of the system if the partial pressure of hydrogen is doubled? As equilibrium reestablishes, would the : a) pressure of CS2 increase, b) pressure of CH4 decrease, c) pressure of H2 decrease, d) pressure of H2S decrease, or e) all the pressures will decrease???
