The discussion centers on calculating the distance a ball travels when kicked off a 20-meter cliff. The ball has a mass of 5 kg and is subjected to gravitational acceleration of 9.80 m/s². The final velocity (v(f)) is calculated to be 10 m/s, and the initial velocity (v(i)) is 0 m/s. The time of flight is determined to be approximately 2.019 seconds, although the impulse value of 50 kg m/s mentioned is questioned as it is not provided in the problem statement.
PREREQUISITESStudents studying physics, educators teaching mechanics, and anyone interested in understanding motion dynamics in real-world scenarios.
How do you know the impulse is 50 kg m/s? The problem statement did not say anything about impulse.RiversAlone said:Homework Statement
A ball weighing 5kg is kicked off a cliff with the height of 20 meters.
What is the distance the ball travels?
Known:
g (gravity) =9.80
I (impulse) = 50kg m/s
m (mass) =5kg
h (height) =20m
How did you get these?Unknown:
