No, it is 4 times as great. Looking at the equation for kinetic energy: E=0.5 x m x v x v
Where E=kinetic energy
m = mass of vehicle
v = velocity of vehicle
If the vehicle weighs 1000 kg and is traveling at 10 m/s the kinetic energy possessed will be 1000 x 10 x 10 = 100,000 joules
Whereas if the same vehicle is traveling at 20 m/s it would be 1000 x 20 x 20 = 400,000 joules. In other words, the vehicle possesses four times as much energy.

If 2 identical cars crash and each is traveling at 50 mph is the impact speed 50 mph or 100 mph and why?
The impact speed for each car is 50 mph. During the crash, both cars are accelerated from a speed of 50 mph to zero, hence the impact speed is 50 mph. The relative speed between each car, however, is 100 mph.
Is Being in a crash at 30 MPH has the equivalent force of being dropped off a four story building?
well if you were dropped off a 4story building you would probly die but a car crash is kinda different so i guess you would die in a car crash if you were a little kid but if you arent then i don't think you will
Is it true that being in a crash at 30 mph has the equivilent force of being dropped off a four story building?
Yes, its true. I had driver's ed, and my teacher explained to us the mechanics.
