Question

Alex, a mountaineer, must leap across a wide crevasse.(Figure 1) The other side of the crevasse is below the point from which he leaps, as shown in the figure. Alex leaps horizontally and successfully makes the jump. Determine the algebraic sign of Alex's x velocity and y velocity at the instant he leaves the ground at the beginning of the jump. A)Type the algebraic signs of the x velocity and the y velocity separated by a comma (examples: +,- and 0,+). B)Determine the algebraic signs of Alex's x velocity and y velocity the instant before he lands at the end of the jump. C) Determine the algebraic signs of the ball's x velocity and y velocity the instant after it leaves the player's hands. D) Determine the algebraic signs of the ball's x velocity and y velocity at the ball's maximum height.
