Starting at the same time, an arrow and a ball are shot horizontally with a speeds of 50 m/s and 44 m/s respectively from the top of a building over flat ground. Which best describes what happens? A. The arrow and the ball land the same distance from the building at different times. B. The arrow and the ball land at different distances from the building at different times. C. The arrow and the ball land the same distance from the building at the same time. D. The arrow and the ball land at different distances from the building at the same time.

Respuesta :

Answer:

option D

Explanation:

given.

horizontal velocity of arrow and a ball given as  50 m/s and 44 m/s respectively from the top of a building over flat ground.

In vertical direction, they are both identical

In vertical direction the initial velocity of arrow and a ball  is 0  m/s

Their acceleration due to gravity  is same for both arrow and a ball  9.8 m/s²

they will react bottom at the same time

 time of flight is same for both

now,

In horizontal direction,

distance = speed × time

Since speed is more for arrow, it will travel more horizontal distance  at the same time.

the correct answer is option D
