Question

A ball is thrown horizontally off the roof of a 125m building to a catcher who is on street level. If that person is standing 50m away, how long did it take for the ball to reach the catcher?

a) 2.24 seconds
b) 3.18 seconds
c) 3.65 seconds
d) 4.47 seconds"

Answer 1

The ball will take an infinite amount of time to reach the catcher as it has an initial horizontal velocity of 0 m/s.

Step-by-step explanation:

To solve this problem, we can use the equation for horizontal distance traveled in projectile motion, which is given by:

distance = velocity * time

In this case, the distance traveled horizontally is 50m and the velocity in the x-direction is the initial velocity of the ball. Since the ball is thrown horizontally, the initial velocity in the y-direction is 0 m/s. Using the equation for time, we can solve for the time it takes for the ball to reach the catcher:

time = distance / velocity

Substituting the values, we have:
time = 50m / 0 m/s = undefined

Since the ball has an initial horizontal velocity of 0 m/s, it will take an infinite amount of time for the ball to reach the catcher. Therefore, the correct answer is not among the options given.
