In a collision, the human body will strike the seatbelt, steering wheel, dash, or windshield at the same speed as the vehicle.

A collision is when one object comes in contact with another, leading to an abrupt and forceful impact. This means that a collision happens when one object hits another surface or object with an extreme impact that causes injuries or damages.

  • There are three theories of collision, among which the "human collision" is the second theory.
  • In this theory, the impact of a collision between the human body and the external surface happens after the collision occurs.
  • But the force of the impact remains the same, meaning the force with which the body hits the other surface is at the same speed as the vehicle prior to the collision.
  • This is because while the collision may have occurred, the body is still moving at the same speed as the vehicle, thereby resulting in the same speed of the vehicle as that of the force of impact.
  • So, the <u>human body will strike the external or opposite surface at the speed of the vehicle</u>.

Prior to a collision, the body inside the vehicle is moving at the speed of the vehicle. So, when a collision occurs, the <u>body continues to move with that speed</u> even though the vehicle may have halted. Thus, <em>the human body will strike at the same speed as the vehicle</em>.

zzz [600]
The solution for this problem is:

For 1st minimum, let m be equal to 1. 

d = slit width

D = screen distance. 

Θ = arcsin (m * lambda/ (d))


= 0.13934 rad, 7.9836 deg 

y = D*tan (Θ)

y = 6.50 * tan (7.9836)

= 0.91161 m is the distance from the central maximum to the first-order minimum

Freight car A with a gross weight of 200,000 lbs is moving along the horizontal track in a switching yard at 4 mi/hr. Freight ca
zhenek [66]

Answer: a) 4.7 mi/hr.  b) 86,500 lbs. mi²/Hr²

Explanation:

As in any collision, under the assumption that no external forces exist during the very small collision time, momentum must be conserved.

If the collision is fully inelastic, both masses continue coupled each other as a single mass, with a single speed.

So, we can write the following:

p₁ = p₂ ⇒m₁.v₁ + m₂.v₂ = (m₁ + m₂). vf

Replacing by the values, and solving for vf, we get:

vf = (200,000 lbs. 4 mi/hr + 100,000 lbs. 6 mi/hr) / 300,000 lbs = 4.7 mi/hr

If the track is horizontal, this means that thre is no change in gravitational potential energy, so any loss of energy must be kinetic energy.

Before the collision, the total kinetic energy of the system was the following:

K₁ = 1/2 (m₁.v₁² + m₂.v₂²) = 3,400,000 lbs. mi² / hr²

After the collision, total kinetic energy is as follows:

K₂ = 1/2 ((m₁ + m₂) vf²) = 3,313,500 lbs. mi²/hr²

So we have an Energy loss, equal to the difference between initial kinetic energy and final kinetic energy, as follows:

DE = K₁ - K₂ = 86,500 lbs. mi² / hr²

This loss is due to the impact, and is represented by the work done by friction forces (internal) during the impact.

What is the definition of work when net force is parallel to the distance?
goldfiish [28.3K]
Work in general is given by W=F·d where F is the force vector and d is the displacement vector.  The dot symbol is the dot product which is a measure of how parallel two vectors are.  It can be replaced by the cosine of the angle between the two vectors and the vectors replaced by their magnitudes.  If F and d are parallel then the angle is zero and the cosine is unity.  So in this case work can be defined as the product of the magnitudes of the force and distance:
