What has more kinetic energy a 0.0018-kg bullet traveling at 402 ms or a 6.8 107-kg ocean liner traveling at 10 ms 19 knots?
For an object of mass m (measured in kilograms, kg) travelling at a speed v (measured in metres per second, m s-1), assuming that v is well below the speed of light, the kinetic energy E (measured in joules, J) is given by:
E = 1/2 m v2
So for the bullet, m = 0.0018 kg, and v = 402 m s-1:
E = 1/2 x 0.0018 kg x (402 m s-1)2
= 145.4436 J
For the ocean liner, assuming m = 6.8 x 107 kg (68 000 000 kg), and v = 10 m s-1:
E = 1/2 x 68 000 000 kg x (10 m s-1)2
= 3 400 000 000 J
So the bullet has a kinetic energy of around 145 joules, and the ocean liner has a kinetic energy of 3.4 billion joules. To answer the question, the ocean liner has more kinetic energy than the bullet.

What energy is in a traveling bullet?
A traveling bullet primarily carries kinetic energy due to its motion through the air. This kinetic energy is derived from the initial potential energy stored in the bullet when it was fired.
A bullet traveling upwards has what type of energy?
it has both potential and kinetic energies as when it is going upwards, the potential energy increases while the kinetic energy decreases until it reaches the top, and then the kinetic energy is zero and the potential energy is maximum.
What form of energy does a speeding bullet have?
A speeding bullet has kinetic energy, which is the energy associated with its motion. As the bullet travels, it carries this kinetic energy due to its velocity and mass.
What type of energy is produced from a speeding bullet?
Kinetic energy is produced from a speeding bullet, which is the energy associated with the motion of an object. This energy comes from the bullet's velocity and mass.
What is the kinetic energy in joules of a 0.02 kg bullet traveling 300 miles per second?
The kinetic energy of the bullet can be calculated using the formula: KE = 0.5 * m * v^2, where m is the mass and v is the velocity. Plugging in the values, KE = 0.5 * 0.02 kg * (300 m/s)^2 = 900 J. So, the kinetic energy of the bullet is 900 joules.
What a example of kinetic energy?
A bullet racing by a non moving observer has kinetic energy.
Which energy is possessed by bullet released from a gun?
Kinetic, potential, and heat.
When a bullet is fired from a rifle does the bullet have a greater momentum and kinetic energy than the rifle?
Yes, when a bullet is fired from a rifle, the bullet typically has greater momentum and kinetic energy compared to the rifle. This is due to the bullet's higher velocity and lower mass compared to the rifle.
When a bullet penetrates into a target in which energy its kinetic energy will change?
When a bullet penetrates a target, the bullet's kinetic energy will decrease as it transfers some of its energy to the target. The bullet loses energy as it does work to penetrate the target. Some of the energy is also converted to heat due to friction and deformation of the target material.
When a bullet leaves a gun the bullet has what type of energy?
The bullet has kinetic energy when it leaves the gun, as it is in motion.
What is a example of kinetic?
A bullet racing by a non moving observer has kinetic energy.
What is the Formula for energy of a fired bullet?
The kinetic energy of a fired bullet can be calculated using the formula KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass of the bullet, and v is the velocity of the bullet.
