# Direction of Velocity at Various Times in Flight for Projectile Motion Conceptual Question2 of 4Review | ConstantsFor each of the motions described below, determine the algebraic sign (positive, negative, orzero) of the x component and y component of velocity of the object at the time specified. For all ofthe motions, the positive x axis points to the right and the positive y axis points upward.Alex, a mountaineer, must make it across a wide crevasse. Alex runs horizontally off the edge and successfully makes it to the other side of the crevasse, which is below the point from which he takes off, as shown in (Figure 1)Part ADetermine the algebraic sign of Alex's x velocity and y velocity at the instant he leaves the ground at the edge of the crevasse.Type the algebraic signs of the x velocity and the y velocity separated by a comma (examples: +- and 0,+).View Available Hint(s)SubmitPart BDetermine the algebraic signs of Alex's x velocity and y velocity the instant before he safely lands on the other side of the crevasse.Type the algebraic signs of thex velocity and the y velocity separated by a com(examples: , - and 0,+).View Available Hint(s)Figure1 of 2SubmitAt the buzzer, a basketball player shoots a desperation shot.
