Is it possible for two cars to collide at 50 mph?
I imagine that either crash is very likely to be fatal at that speed. Addressing your new question, two cars crashing head-on each at 50 mph is essentially the same as one car going 100 mph and crashing into a stationary car, by the relativity principle.
Which is safer a car crash at 50 mph or 100 mph?
In this case, though, simple considerations do reveal that the car-car crash at 50 mph is almost certainly safer than crashing 100 mph into a wall. Your energy calculation is a fine way to see this. Another is to consider the car-car collision from a frame co-moving with the second car.
What happens if you collide with a wall at 50 mph?
In the car against a wall, you do have the full dissipation of a kinetic energy of 4 × 1 2 m v 2. Actually, assuming that the oncoming car is the same mass as yours, colliding with an oncoming car at 50 MPH is equal to colliding with an ideal immovable wall at 50 MPH. Consider this:
How much kinetic energy does a car have before a crash?
From the reference frame moving with the first car, the kinetic energy before the crash is 1 2 m ( 2 v) 2 = 4 × 1 2 m v 2, but after the crash the cars do not remain at rest, but keep moving in the direction of the second car at half the speed.
How many miles per minute can a vehicle travel?
Q: Then you have to close in and underscore how the defendant is contradicting himself/herself; the court has taken judicial notice of how far vehicles can travel over time at given speeds. You would agree that at 30 mph a vehicle is traveling at 2 miles per minute.
What’s the average speed of a car at 30 mph?
You would agree that at 30 mph a vehicle is traveling at 2 miles per minute. A: Yes. Q: And there are 1760 yards in a mile? (The witness is using yards here. If feet, there are 5,280 feet in a mile?) A: Yes. Q: So at 30 mph, a vehicle is traveling less than 15 yards per second? A: I suppose. Q: So you had maybe four seconds before the impact?
What’s the safe following distance at 55 mph?
Safe Driving Distance at 55 MPH in Good Conditions The rule of thumb is to maintain at least a three-second following distance, giving you time to react and avoid potentially dangerous situations. You can calculate this by using a fixed object, such as a pole or an overpass to determine how far in front of you the car is.
How many car lengths does it take to stop at 20mph?
The distances are based on the average car length in the UK and assume the road is dry. The stopping distance at 20mph is around 3 car lengths. At 50mph it’s around 13 car lengths. If you’re travelling at 70mph, the stopping distance will be more like 24 car lengths.
