The relevant equations are
d=1/2 at2 and
v = at.
Substituting t = v/a into d=1/2 at2 gives
d = v2/2a.
This formula will give the drop height d for any desired speed v.
Plugging in
v = 20mph = 8.9408m/s;
a = 9.8 m/s2 (this is the gravitational acceleration at the earth's surface)
we get
d = 4.078m = 13.38 feet.

In a head-on collision where both cars are traveling at 55 mph the combined closing speed would equal?
The bigger the tire and heavier the car the car will slide in slippery road conditions
How many miles over 50 increases collision?
Driving just 10 miles per hour over the speed limit can significantly increase the risk of a collision. Studies show that the likelihood of an accident doubles for every 10 mph above 50 mph. Therefore, exceeding 50 mph by even a small margin can substantially elevate the chances of a crash, particularly due to reduced reaction time and increased stopping distance.
How fast does an object fall if it takes 3 seconds to drop 200 feet?
45.5 mph
How fast does a person fall after falling from a height of 40 feet?
The answer to that is 40-56 mph i quess
How many mph are you walking if you walked 1.5 miles in 30 minutes?
1.5 miles in 30 minutes is equivalent to 3 miles in 60 mintes = 1 hour.So the average speed is 3 mph.1.5 miles in 30 minutes is equivalent to 3 miles in 60 mintes = 1 hour.So the average speed is 3 mph.1.5 miles in 30 minutes is equivalent to 3 miles in 60 mintes = 1 hour.So the average speed is 3 mph.1.5 miles in 30 minutes is equivalent to 3 miles in 60 mintes = 1 hour.So the average speed is 3 mph.
How many times greater is the impact of a collision at 60 mph compared to 30 mph?
The impact of a collision at 60 mph is four times greater than at 30 mph.
In a head on collision what is the combined closing speed of 2 people going 55 mph?
The combined closing speed in a head-on collision between two people traveling at 55 mph each would be 110 mph. This is the sum of the speeds of the two individuals as they approach each other from opposite directions.
What is the risk of death in a traffic collision doubled over 50 mph?
double
What is the top speed in mph on a snowboard?
156 mph on a 16 foot drop of a half pipe
400 mph is equivalent to meters per second?
400 mph is equivalent to 178.8 meters per second.
How fast do you drop in Tower of Terror?
Around 40 MPH
How many mph does an airbag come out?
On Ford vehicles the airbags typically deploy at 25 to 30 MPH, so in a head on collision, if both vehicles are traveling at a slow 15 MPH your airbags will go off
Drive 1 mile in 72 seconds what is mph?
It is equivalent to 50 mph.
Is it true that if two cars collide while approaching each other at 60 mph that the impact is equivalent to one car hitting a solid steel wall at 120 mph?
No, when two cars collide while approaching each other at 60 mph, the impact would be equivalent to one car hitting a solid steel wall at 60mph.Newtons third law states that for every action there is an equal and opposite reaction. When a car is traveling at 60 mph and hits a solid steel wall, the wall applies a force equal to 60 mph back toward the car. This is the same as if a car that is traveling at 60 mph hits another car traveling at 60 mph. In both scenarios, the car is traveling at 60 mph and at the point of collision a force equal to 60 mph is imparted on the car.
How fast is 6 kmh in mph?
6 km/h is equivalent to approximately 3.73 mph.
Collision at 30 MPH will take any loose object in your car?
A collision at 30 MPH can lead to loose objects in your car becoming projectiles, increasing the risk of injury to vehicle occupants. To minimize this risk, securely store loose objects in the car, such as using a trunk organizer or keeping items in the glove compartment.
What is the equivalent to 70 knots in mph?
1 mph = 0.868976242 knots70 times .869 = 60.83, so just over 60mph
