Kinetic Energy
No, the energy of a moving car is proportional to the square of its speed. So, a car traveling at 60 mph carries four times the energy as the same car traveling at 30 mph.
Kinetic energy is given by 1/2 M x V2, that is one half mass x velocity squared
Main type is kinetic energy.It may contain sound energy
No, when two cars collide while approaching each other at 60 mph, the impact would be equivalent to one car hitting a solid steel wall at 60mph.Newtons third law states that for every action there is an equal and opposite reaction. When a car is traveling at 60 mph and hits a solid steel wall, the wall applies a force equal to 60 mph back toward the car. This is the same as if a car that is traveling at 60 mph hits another car traveling at 60 mph. In both scenarios, the car is traveling at 60 mph and at the point of collision a force equal to 60 mph is imparted on the car.
No, Car B will not overtake Car A because they are moving at the same speed. They will maintain the same distance between them as long as both continue to travel at 60 mph.
No, the energy of a moving car is proportional to the square of its speed. So, a car traveling at 60 mph carries four times the energy as the same car traveling at 30 mph.

Kinetic energy is given by 1/2 M x V2, that is one half mass x velocity squared
When your car is traveling at a constant speed of 55 mph, your body inside the car is also moving at 55 mph relative to the car. This is because you are moving along with the car, experiencing the same speed as the vehicle you are in.

We know that the time traveled is 5 hours, since a car going 10 mph faster travels an extra 50 miles over the same amount of time.Dividing 300 miles by 5 hours, we get 60 mph. Since the car is traveling 10 mph, the car is traveling 70 mph.
60/15 = 4The KE of an object is proportional to the square of its speed.Multiplying the speed by 4 increases the KE by (4)2 = 16 .
