Question
A bullet with mass $12.0 \mathrm{~g}$ travels $415 \mathrm{~m} / \mathrm{s}$. Find its kinetic energy. (Hint: Convert $12.0 \mathrm{~g}$ to $\mathrm{kg} .)$
Step 1
We know that 1 gram is equal to 0.001 kilograms. So, the mass of the bullet in kilograms is $12.0 \times 0.001 = 0.012 \, \mathrm{kg}$. Show more…

A bullet with mass 12.0 g travels 415 m/s. Find its kinetic energy in J.
(a) Calculate the kinetic energy, in joules, of a 15-g bullet moving at $120 \mathrm{~m} / \mathrm{s}$. (b) Convert this energy to calories. (c) When the bullet is stopped by a bulletproof vest, which form of energy does the kinetic energy of the bullet convert to?
Calculate A $9.50-\mathrm{g}$ bullet has a speed of $1.30 \mathrm{~km} / \mathrm{s}$. What is the kinetic energy of the bullet?
