Car b is following car a and has a greater speed than car a. the two cars are moving in a straight line and in the same direction, and have the same mass. in situation one, car a is traveling at 10 mph and car b at 20 mph. in situation 2, car a is traveling at 30 mph and car b at 40 mph. assuming a perfectly inelastic collision in which the cars stick together after the collision, what will be true?

Collision force will be same in both the cases.

Explanation:

A perfectly inelastic collision is said to take place  when a system loses the amount of its Kinetic Energy at its maximum. In a perfectly inelastic collision,  the colliding particles stick to each other. In such a collision, kinetic energy is lost by combining the two bodies with each other.

In situation 1:

Speed of Car A,

Speed of Car B,

Relative speed of car A and car B,

Now, in the situation 2:

Speed of car A,

Speed of car B,

Relative speed of car A and car B,

Therefore, Car A and Car B both have the same relative speed, v = 10 m/s

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
