A boy jumps off a high diving board above a swimming pool. Halfway between the board and the water he tosses a ball up-ward. Ignoring air friction, the instant after the ball leaves his hands the vertical component of the acceleration of the ball(A) is positive, but then decreases through zero to -9.8 m/s2.(B) is zero, but then decreases to – 9.8 m/s2.(C) is between zero and -9.8 m/s2, but then decreases to -9.8 m/s2.
