Answer:
C
Step-by-step explanation:
I am assuming both of these balls weigh the same.
Gravity is accelerating both balls downward at -9.8m/s^2
I am assuming this thrown ball was thrown horizontally. In this case, there is no horizontal acceleration with projectile motion. There is still, however, gravity accelerating the ball downward at the same rate.
The thrown ball may travel more distance sideways, but they will hit the ground in the same instant.
