Will two cars traveling at the same speed come to rest at the point of impact in a frontal collision?

In general, they will not. Remember that momentum must be conserved, and momentum is the product of mass x velocity. If the cars happen to have the same mass, as well as the same speed, then their combined momentum will indeed be zero. But if one of the cars has a larger mass, their total momentum before the collision will NOT be zero, so the combined cars (after the crash) will continue moving for a while, until slowed down by friction.

No, two cars traveling at the same speed will not come to rest at the point of impact in a frontal collision. The impact will cause both cars to decelerate rapidly, but they will continue to move forward after the collision due to the conservation of momentum. The final resting positions will depend on the specific details of the collision.

How does addition in mass to a car will affect the collision point?
Gravity and mass are a direct modifier and multiplier and can contribute to a stationary collision point after the collision has taken place. The materials the vehicle is made of can also effect the collision point by which materials effect the mass of the moving object during impact.
Is it true that if two cars collide while approaching each other at 60 mph that the impact is equivalent to one car hitting a solid steel wall at 120 mph?
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.
What controls the point of impact of an electron beam?
The Yoke
If two toy cars of the same mass are moving from the opposite directions will they collide at a half way point and what will happen after the collision?
Momentum will be conserved (it always is conserved). If the cars also move at the same speed, and the collision is inelastic, they will both stop completely.
What does a sound wave traveling through air transfer?
Vibrational energy or disturbance produced at one point has been transferred.

The point of which one objects hits or collides with another object. (The point of impact).
How do you setup infant car seat in the car?
Attach the back strap of the infant seat to the anchor point in the back of your vehicle (see your vehicle handbook for its location) then place the adult type seatbelt through the fittings in the infant seat. Please note that an infant seat can't be placed where there is a frontal collision airbag fitted.
What is a meteor and why is it different from a meteorite?
A meteor is a space body traveling through Earth's atmosphere leaving a glowing trail. A meteorite is the solid remnant of a meteor should it survive to the point of impact with Earth's surface.
Why collision time and relaxation time are not equal in anisotropic medium?
average time, an electron spends between two successive collision, is called relaxation time and time spent by electron at point of contact, is called collision time

At the point when it is closest to the sun.
