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
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.
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.

do 60x45 (60 seconds in a minute X 45 minutes) 2700 seconds in 45 minutes
The speed of 45 km/h states that in every hour = 60 minutes = 3600 seconds the car travels 45 km. So in 6 seconds it travels 6/3600 = 1/600 this distance, that is: 45 x 1/600 = 45/600 = 3/40 = 0.075km = 75m.
in about three miles

45
1 minute = 60 seconds 1 hour = 60 mins → 45 mins 45 seconds = 45 + 45/60 mins = (45 + 45/60)/60 hours = 61/80 hours distance = speed × time → distance = 56 mph × 61/80 hours = 42.7 miles.
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.
