If a projectile with a mass of 9.30 g is traveling at a speed of 1.26 km/s, determine the following. (a) the kinetic energy (in kJ) of the projectile in kilojoules kJ (b) the kinetic energy (in kJ) of the projectile in kilojoules, if its speed is reduced by a factor of two kJ (c) the kinetic energy (in kJ) of the projectile in kilojoules, if its original speed is increased by a factor of three kJ If a projectile with a mass of 9.30 g is traveling at a speed of 1.26 km/s, determine the following.
