a vertical velocity toward the surface of the moon of 35.4 m/s. At the same time, it has a horizontal velocity of 57.2 m/s.

At what speed does the vehicle move along

its descent path?

At what angle with the vertical is its path?

**drwls**, Monday, October 10, 2011 at 8:46amFor the speed, use the Pythagorean theorem. You have been given two perpendicular components and you want the hypotenuse.

The angle with the vertical is

arctan 57.2/35.4= 58 degrees
