4 times.
Double the speed yeilds double the impact force.
Yes. (1/2 mass x velocity squared)
60mph unless slower speed limits are in force.
force of impact basiclly means that a force is impacting something! ~hope it helped(:
4 times the impact. The formula is 1/2 mass times velocity squared.
double
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.
trr
depends on the mass of the train
when a car is speeding up how does the forward force and air resistance compare
Pretty sure this is true...let me guess, the drug and alcohol test? I'm taking it too.
No. Frictional force is independant of surface area.
