Ayala · Answer 1

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
