The fractional kinetic energy will be lost if the collision is inelastic. In inelastic collision, the kinetic energy is converted into other forms of energy.
The lost energy became heat and sound energy.
Explanation:
During inelastic collision, the kinetic energy of a moving object does not conserve. It changes into another form of energy such as sound energy and heat energy etc.
For example, when a moving car hit another car or wall etc, the kinetic energy is converted into sound and heat energy. This type of collision is inelastic collision.
Stephen`s Law: P = (Sigma) · A · e · T^4 P in = P out e = 1 for blacktop; 1150 W = (Sigma) · T^4 (Sigma) = 5.669 · 10 ^(-8) W/m²K^4 T^4 = 1150 : ( 5.669 · 10^(-8) ) T^4 = 202.875 · 10^8 T = 3.774 · 10² = 377.4 K Answer: Equilibrium temperature is 377.4 K.
It is the assessment zone in various security zones where active and passive security measures are employed to identify, detect, classify and analyze possible threats inside the assessment zones.
Applying the work-energy theorem, if we can neglect the friction between truck and road, the total change in kinetic energy must be equal to the work done by the external forces.
This work, is just 4,475 J.
So we can write the following equation:
where m= mass of the truck = 2.5*10³ kg.
So, we can find the speed v, as follows:
b)
The work done by the man, is just the horizontal force applied, times the displacement produced by the force horizontally:
