Which bullet will hit the ground first?
a. The bullet that was fired.
b. The bullet that was dropped.
c.It will be a tie.
d. The question can’t be answered with the information given.
2. Which bullet will hit the ground with the greatest velocity?
a. The bullet that was fired.
b. The bullet that was dropped.
c. It will be a tie.
d. The question cannot be answered with the information given.
3. Which would hit the ground first if this experiment were conducted on the surface of the moon?
a. The bullet that was fired.
b.The bullet that was dropped.
c. It will be a tie.
d.The question can’t be answered with the information given.
4. If the bullets were not identical, but rather the dropped bullet had twice the mass of the other, which bullet would hit the ground first?
a.The bullet what was fired.
b.The bullet that was dropped.
c.It will be a tie.
d.The question can’t be answered with the information given.
Explanation / Answer
(1)
(1)
It will be a tie that means both are reaching same time becuase time depends on height . since both bullet are dropping from same height both are reaching same time
(2)
The bullet that was fired because it has finite horizontal velcoity and as well as same verical velocity as dropped bullet
(3)
it will be tie because The vertical component of the speed is the same.
(4)
It will be a tie.
t = root 2h/g
time of flight does not depends on the mass so both will hit the ground at the same time
