Calculate the kinetic energy of a 64. g bullet moving at a speed of 411. ms. Round your answer to 2 significant digits.

The kinetic energy of the bullet is 5.4 * 10³ J

Explanation:

Hi there!

The equation of kinetic energy is the following:

KE = 1/2 · m · v²

Where:

KE = kinetic energy.

m = mass of the bullet.

v = speed of the bullet.

Let's convert the mass unit to kg so that our result is in Joules:

64 g · (1 kg / 1000 g) = 0.064 kg

Then, the kinetic energy will be the following:

KE = 1/2 · 0.064 kg · (411 m/s) ²

KE = 5.4 * 10³ J
