Answer:
Puesto que la energia cinética traslacional es mucho mayor que la capacidad del chaleco antibalas, la bala atravesaría el chaleco antibalas.
Explanation:
Un chaleco antibalas soporta el disparo de una bala disipando la energía de esta última a través de su propio material. Si sabemos que el chaleco antibalas soporta 120 joules de energía, cabe saber si la energía cinética traslacional es igual o inferior a ese límite, significando que la bala no atravesaría el chaleco.
La energía cinética traslacional de la bala (), in joules, queda expresada con la siguiente fórmula:
(1)
Donde:
- Masa de la bala, en kilogramos.
- Rapidez de la bala, en metros por segundo.
Si sabemos que y , entonces la energía cinética traslacional de la bala es:
Puesto que la energia cinética traslacional es mucho mayor que la capacidad del chaleco antibalas, la bala atravesaría el chaleco antibalas.
Explanation:
wave is a disturbance that carries energy from one particle to another particle. The speed depends on:
1. The type of medium
2. The temperature of the medium
3. The energy of the wave
4. The amplitude of the wave
The kinetic energy of the car is
Explanation:
The kinetic energy of an object is the energy possessed by the object due to its motion.
Mathematically, the kinetic energy is
where
m is the mass of the object
v is its speed
For the car in this problem,
m = 740 kg
v = 33.5 m/s
Therefore, the kinetic energy of the car is

In the combustion chamber of a gas turbine engine the mixture of fuel oil and compressed air is ignited. The combustion chamber is responsible for supplying the energy which drives the system. For a turbine, the combustion chamber operates with periodical combustion and the space, where the combustion takes place is closed on the exhaust side leading to the actual turbine.
