4 times.
Double the speed yeilds double the impact force.
When the speed of a car doubles, the force of impact quadruples due to the relationship between force and kinetic energy (which increases with the square of velocity). This means that a car traveling at 60mph will experience roughly four times the force of impact compared to when it is traveling at 30mph.
At 60mph, it generally takes longer to stop compared to 30mph due to the higher speed and momentum. Factors such as reaction time, braking distance, and road conditions also affect stopping time. In general, stopping at 60mph will take more than twice the distance compared to stopping at 30mph.
60mph unless slower speed limits are in force.
No, the force of impact is not directly proportional to velocity. The force of impact is determined by factors such as the mass of the vehicle and the effectiveness of its brakes in stopping it.
depends on the mass of the train
No, the force of impact is not directly proportional to the speed of the car. In a collision, the force of impact is determined by the change in momentum, which is a combination of speed and mass. Doubling the speed does not necessarily mean quadrupling the force of impact.
4 times the impact. The formula is 1/2 mass times velocity squared.
when a car is speeding up how does the forward force and air resistance compare

The outward force from a surface is called normal force. It is the force exerted by a surface that is perpendicular to the surface and acts to support the weight of an object resting on it.
