A 30 mph missile.
The impact of a collision at 60 mph is four times greater than at 30 mph.
It would take approximately 1,500 feet for an object to reach a speed of 120 mph when free-falling due to the force of gravity.
The only thing that matters is the RELATIVE Velocity between the two Objects, not whether they are BOTH moving or not. If one is standing still and the other going 100 MPH, the result is the same as if both were going 50 MPH.
The speed of a falling object increases by approximately 9.8 meters per second every second, which is equivalent to 22 miles per hour every second. After 1 second, the speed would be 22 mph, and after 2 seconds it would be 44 mph, and so on.
Speed is a scalar magnitude (it only tells you how much). Velocity is composed of the object's speed and the direction in which it's moving. This corresponds to the definition of a vector.Using "miles" and "hours" as an example:"30 miles per hour (mph) " is a speed"30 miles per hour (mph) north" is a velocity"30 mph north" and "30 mph east" are different velocities with the same speed."30 mph north" and "35 mph north" are different velocities/speeds with the same direction.If you add "30 mph" plus "30 mph", you get 60 mph ... maybe.If you add "30 mph north" plus "30 mph south", you get standing still.If you add "30 mph north" plus "30 mph east", you get 42.426 mph northeast, using vector calculations.Therefore, when a vehicle travels on a winding road maintaining a speed of 30 mph, its speed remains the same but its velocity is changing with each turn.

About 38 hours 20 minutes.
2.38 seconds.
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.
double
-10 mph/sec
Hang Loose mon!!
-4 mph/sec (Study Island Answer)
perhaps it is bad hub bearing Tire out of balance, loose lug nuts, worn or loose wheel bearing, defect in a tire, etc.
