5) A ball is thrown vertically upward from the surfaceof the earth. Consider the following quantities: (1) the speed ofthe ball; (2) the velocity of the ball; (3) the acceleration of theball. Which of these is (are) zero when the ball has reached themaximum height? A ) 1, 2, and 3 B ) 2 C ) 1 D ) 1 and 3 E ) 3 F ) 1 and 2 5) A ball is thrown vertically upward from the surfaceof the earth. Consider the following quantities: (1) the speed ofthe ball; (2) the velocity of the ball; (3) the acceleration of theball. Which of these is (are) zero when the ball has reached themaximum height?Explanation / Answer
answer is F at maximum height acceleration is gravitional accelerationand acts downwards on mass maximum height means there velocity has to be zero and speed ismagnitude of velocity whic is also zero at maximum height
