Solution:
Given:
Time taken by the first ball to reach the ground = 6 s
Time taken by the second ball to reach the ground = 1.5 s
Let's analyze each ball's motion separately to understand their behavior.
First Ball:
- The first ball is thrown vertically upward from the top of the tower.
- The motion of the ball is influenced by the gravitational force, which acts in the downward direction.
- As the ball moves upward, it slows down due to the gravitational force acting against its motion.
- At the highest point of its trajectory, the ball momentarily stops before starting to fall back down.
- The total time taken by the ball to reach the ground is 6 s.
Second Ball:
- The second ball is thrown vertically downward from the same position with the same speed as the first ball.
- The motion of the ball is solely influenced by the gravitational force, which acts in the downward direction.
- Since the ball is thrown downward, its initial velocity is negative.
- The ball accelerates due to gravity, and its speed increases as it falls.
- The total time taken by the ball to reach the ground is 1.5 s.
Third Ball:
- The third ball is released from rest from the same location.
- Since the ball is released from rest, its initial velocity is zero.
- The motion of the ball is solely influenced by the gravitational force, which acts in the downward direction.
- As the ball falls freely, it accelerates due to gravity.
- The time taken by the ball to reach the ground can be calculated using the equation:
t = sqrt((2h)/g)
where t is the time taken, h is the initial height, and g is the acceleration due to gravity.
- Since the initial height is the same as the height of the tower, the time taken by the third ball to reach the ground is 3 seconds.
Therefore, the third ball will reach the ground in 3 seconds.
