9.5 g bullet has a speed of 1.5 km/s what is the kinetic energy of the bullet

Respuesta :

The answer is  0.000824653J

You need to use the formula Mass * Velocity^2 over 2


Answer:

The kinetic energy of the bullet is approximately 10688 Joules, or about 10.7kJ.

Explanation:

Use the kinetic energy formula:

[tex]E_k=\frac{1}{2}mv^2= \frac{1}{2}9.5\cdot10^{-3}kg\cdot 1.5^2\cdot 10^6 \frac{m^2}{s^2}\approx 10688J[/tex]

The kinetic energy of the bullet is approximately 10688 Joules, or about 10.7kJ.
