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.

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 hours is 3000 miles equivalent to?
That depends on the speed you're travelling at in 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.

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
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.
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?
Yes, in an idealized scenario where two identical cars collide head-on at equal speeds, the impact would be equivalent to one car hitting a solid wall at the combined speed of both cars. This is due to the concept of relative velocity and the transfer of kinetic energy during the collision.
