Question
Which has more kinetic energy: a 0.0018-kg bullet traveling at 403 m/s or a 5.3 107-kg ocean liner traveling at 10 m/s (19 knots)?
the bullet has greater kinetic energythe ocean liner has greater kinetic energy
Justify your answer.
| Ek-bullet | = | J |
| Ek-ocean liner | = | J |
Expert Solution
Step 1
As we know kinetic energy involved the motion. Therefore the formula we are going to use to calculate kinetic energy is:
Kinetic Energy(Ek) =1/2 × (Mass)(Velocity)2
For a bullet :
Mass of bullet = 0.0018 kg
Velocity of bullet = 403 m/s
