Part A
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.
Type the algebraic signs of the x velocity and the y velocity separated by a comma (examples: +,- and 0,+ ).
Part B
Determine the algebraic signs of Alex's x velocity and y velocity the instant before he lands at the end of the jump.
Type the algebraic signs of the x velocity and the y velocity separated by a comma (examples: +,- and 0,+ ).
At the buzzer, a basketball player shoots a desperation shot. The ball goes in!
Part C
Determine the algebraic signs of the ball's x velocity and y velocity the instant after it leaves the player's hands.
Type the algebraic signs of the x velocity and the y velocity separated by a comma (examples: +,- and 0,+ ).
Part D
Determine the algebraic signs of the ball's x velocity and y velocity at the ball's maximum height. Type the algebraic signs of the x velocity and the y velocity separated by a comma (examples: +,- and 0,+ ).
