Question

From the top of a tall building (height > 100 m), ball A is launched with a velocity of 20 m/s at an angle of 45° above the horizontal direction, ball B is launched with a velocity of 20 m/s in the horizontal direction, and ball C is launched with a velocity of 20 m/s at an angle of 45° below the horizontal direction. All of the balls are identical and launched at exactly the same time, t = 0 seconds. Which of the following choices correctly relates the range for the three balls? Ignore any effects of air resistance

Explanation / Answer

Range of ball C < range of ball B < range of ball A
