The answer to this questios depends on what the force of gravity is where you are at.
On earth the force of gravity causes an acceleration of 9.81 meters/second2(32.2ft/s2).
With this information you can use the physics equation d=do+vot+1/2at2, where:
d: distance the rock has travelled
do: initial distance of rock
vo: initial velocity(speed) of the rock
a: acceleration of rock(in this instance due to gravity)
t: time being considered.
For you question we will assume the rock was initially at rest and that the rock will not hit ground in 4.5 seconds. The equation then becomes d=0+(0*4.5)+(0.5*9.81*4.52).
solving for d you will get d=99.4 meters or 326.0 feet

How far can a car go at 45 mph in 3 seconds?
1 miles = 1760 yards 1 hour = 3600 s Distance = speed × time = 45 mph × 3 s = 45 miles/hours × 3 seconds = 45 × (1760 yards)/(3600 seconds) × 3 seconds = 45 × 1760/3600 × 3 yards = 66 yards.
How far does a car travel in 5 seconds at 45 mph?
45 mph = 45 miles/hour (45 miles/hour) (1hr/60 minutes) (1 minutes/60 seconds) (5 seconds) = 0.0625 miles in 5 seconds Note: If you write the fractions above with a horizontal slash instead of a diagonal slash, it is easier to see what cancels out to make this problem work the way it does.
How many seconds are there in 45 years?
About 1,420,092,000 seconds in 45 years.
How do you find out how many seconds are in 45 mins?
do 60x45 (60 seconds in a minute X 45 minutes) 2700 seconds in 45 minutes
45 seconds equal how many hours?
45 seconds is 0.0125 hours.
