a) What is the kinetic energy of a 20.0 g bullet moving with a speed of 150 m/s? b) How much work is needed to stop the bullet? A bullet of mass 10.8 g leaves a gun barrel with a velocity of 511 m/s. What is the bullet's kinetic energy? answer in joules ...
work is in joules (N*m) (or calories, but we are using primarily SI units) opposing force is in newtons (kg*m/s2) displacement is in metersIn chemical reactions, work is primarily related with expansion. It is generally defined as : ...
