Question

While doing an experiment, Tom drops a ball cut of a window 2.3 meters above the ground. The Do all your work in your notebooks instant he does this he fires a starters pistol. Jerry sees the ball hit the ground at the instant he hears the pistols shot. The speed of pistol's sound is 334 m/s -it is constant and wil not change. a. How long did it take for Tom's ball to reach the ground? b. How far away was Jerry standing?

Answer 1

a. The time it takes for the ball to reach the ground is calculated using the equation

t = d/v

Where t is time, d is the distance the ball has to travel, and v is the speed of the sound.

In this case, d = 2.3 meters and v = 334 m/s

Therefore, t = 2.3/334 = 0.0069 seconds.

b. The distance Jerry was standing away from the window is equal to the speed of sound multiplied by the time it took for the ball to reach the ground.

d = vt

Therefore, d = (334 m/s)(0.0069 s) = 2.3 meters.

Therefore, Jerry was standing 2.3 meters away from the window.
