A descent vehicle landing on the moon has a vertical velocity toward the surface of the moon of 29.6 m/s. At the same time, it has a horizontal velocity of 54.8 m/s. At what speed does the vehicle move along its descent path?
If the vertical component is 29.6 m/s down, and the horizontal component is 54.8 m/s parallel to the surface, then the magnitude of the slanty vector is
