We know that S=ut+.5gt*t here s=84m g=9.8m/s*s u=0 hence time is 4.14secs.
3 or 2 minute take to this distance.
long enough
0.95 - 1.05 secs
"3.2" or "3.20" please put all of that
t matters how much mass the ball has
The answer depends on whether the ball is thrown vertically upwards or downwards. That critical piece of information is not provided!
It depends on what height you drop it from.

To answer this question and ones like it, try exaggerating. Does it take the same amount of force to throw a cannon ball 3 meters as it does to throw a golf ball 3 meters?
You didn't tell us how long it took to walk those 3.33 meters, so it is impossible to know how long 100 meters would take.
Depending on the value used for the acceleration due to gravity (9.8 ms-2 or 9.81 ms-2), the ball will go up to 11.48 m or 11.47 m (approx). It will be in the air for a total of 3.06 seconds.
speed = distance/time --> time = distance/speed = (30 m)/(50 m/s) = 0.6 seconds
