Weight = mass × gravitational field strength
At space gravitational field strength is very low so its"weightless".
Answer:
8.953 s
Explanation:
Here a time of 8953 ms is given.
Some of the prefixes of the SI units are
mili = 10⁻³
micro = 10⁻⁶
nano = 10⁻⁹
kilo = 10³
Mega = 10⁶
Each prefix increases or decreases by a factor of 10³
The number is 8953.0
Here, the only solution where the number of significant figures is mili. If any other prefix is chosen then the significant figures will increase.
So, 8953 ms = 8.953 s
In a vacuum they would fall at the same speed, but since it is only off the empire State building, the hammer would fall first

Given
The projectile is in air for a time of t=8 sec
To find
The time it takes to reach the highest point
Explanation
A projectile moves up to the highest point and then again moves down following a parabolic path.
So it will reach the highest point at a time half the time it requires to follow teh parabolic path.
The time taken to reach the highest point is 4 sec
Conclusion
The time taken is 4 sec.
