How far will the car skid with locked brakes at 90 miles per hour if A car at 30 miles per hour skidds 40 feet with locked brakes?
There isn't a direct linear relationship between speed and stopping distance with locked brakes. The stopping distance increases exponentially with speed due to factors like increased kinetic energy and reduced tire grip at higher speeds. It's not accurate to calculate the stopping distance at 90 mph just by extrapolating from the data given for 30 mph. Specialized calculations or tests are needed to determine the stopping distance at 90 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.
How do you convert time to MPH?
To convert time to miles per hour (MPH), you need to know the distance traveled. Then, divide the distance by the time in hours. For example, if you travel 60 miles in 2 hours, you would divide 60 by 2 to get 30 MPH.
How does an object's speed differ from its velocity?
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.
How does speed affect stopping?
The faster you are going the longer the stopping distance is. The slower you are going the shorter the stopping distance is. E.G. Speed of a car Thinking distace Breaking distance Total stopping distance mph meters meters meters 30 9 14 23 40 12 24 36 50 15 38 53 70 21 75 96
What is the Stopping distance at 30 mph?
Stopping distance at 30mph = 23m
What is the stopping distance for a vehicle traveling at 30 mph?
When traveling 30-mph, the braking distance is 45-feet, and the total stopping distance is 75-feet. This is the length of a semi-truck and trailer.
Stopping distance at 30 mph?
23 meters on a dry pavement.
What is the stopping distance for a car travelling at 30 mph?
23 meters in normal conditions
Total stopping distance on dry pavement at the speed of 30 mph is about?
The total stopping distance for a car travelling at 30 mph on a dry surface is about 75 feet. However, you may wish to note that in most countries, driving a car on the pavement is illegal.
What is the typical stopping distance at 70 mph?
Stopping Distance = about 315 feet at 70 mph
An average freight train traveling at 30 MPH needs a stopping distance of more than?
1/2
How does kinetic affect the stopping distance of a vehicle traveling at 30 mph compared to the same vehicle traveling at 60 mph?
The kinetic energy of the vehicle when it is travelling faster is four times as great. It the brakes apply the same retardation and the friction from the tires on the road surface is unchanged then the stopping time will be four times as long.
If i drive 75 miles at 30 mph how long will it take?
1 mile at 30 mph is 2 minutes because it is 1/30th of a mile and when it is 60 minutes divided by 30mph = 60/30 which equals 2 minutes. About 2 hours 30 minutes. This is the driving time at that speed and does not include slowing, accelerating or stopping during the trip.
What would your stopping distance be if you are driving 30 miles per hour?
Most cars can stop from 60 mph in about 100 feet or so. If the relationship is linear then a car should stop from 30 mph in about 50 feet.
What is the stopping distance at 10 mph?
Stopping Distance = 15 feet
How long would it take to drive 100 miles at 40 mph?
About 2 hours 30 minutes. This is the actual driving time at that speed and does not include slowing, accelerating or stopping during the trip.
