Question...which one travels faster?
I had this question on a homework assignment and I was hoping someone could help me understand why I got it wrong.
A ball is thrown down from a building and another ball is thrown up with the same amount of velocity. What is their speed when they hit the street?
a. the one thrown up is traveling faster
b. the one thrown down is traveling faster
c. the speeds are the same
d. cannot be determined
The answer I chose was [a] because it is going to travel up until the velocity reaches zero at which point it will fall a greater distance (therefore gaining more speed on the way down) than that of the ball initally thrown down.
Please correct me if I am wrong and tell why. Thank you and have a nice day!
