For each of the motions described below, determine the algebraic sign (positive, negative, or zero) of the x component and y component of velocity of the object at the time specified. For all of the motions, the positive x axis points to the right and the positive y axis points upward. Figure L. < 1 of 2 Alex, a mountaineer, must make it across a wide crevasse. Alex runs horizontally off the edge and successfully makes it t other side of the crevasse, which is below the point from which he takes off, as shown in (Eigure 1). Part A Determine 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) Submit Part B Determine the algebraic signs of Alex's x velocity and y velocity the instant before he safely lands on the other side of crevasse. Type the algebraic signs of the x velocity and the y velocity separated by a comma (examples: +, - and e,+). View Available Hint(s) Submit P Pearson
