Question

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

Answer 1

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

Step-by-step explanation:

Use the kinetic energy formula:

`E_k=(1)/(2)mv^2= (1)/(2)9.5\cdot10^(-3)kg\cdot 1.5^2\cdot 10^6 (m^2)/(s^2)\approx 10688J`

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

Answer 2

The answer is 0.000824653J

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