A bullet of mass 50g is moved with a velocity of 500 m/s. It penetrates 10 cm into the still target.
Added by Sean G.
Step 1
First, we need to find the kinetic energy of the bullet before it penetrates the target. The formula for kinetic energy is: KE = (1/2)mv^2 where m is the mass of the bullet (50g = 0.05kg) and v is its velocity (500m/s). Show more…
