Which has more kinetic energy a 0.0020-kg bullet traveling at 400 ms or a 6.4 X 10 7 -kg ocean liner traveling at 10 ms 20 knots?

Let's see.
KE = 1/2mV^2
Bullet:
KE = 1/2(0.0020 kg)(400 m/s)^2
= 160 Joules
-------------------------------
Ocean Liner:
KE = 1/2(6.4 X 10^7 kg)(10 m/s)^2
= 3.2 X 10^9 Joules
-----------------------------
The linear by a long shot!

What is the kinetic energy of a 22500 lb truck traveling 55 mph?
The kinetic energy of a 22500 lb truck traveling 55 mph is 1/2mv2 is 3084.808kJ.
Describe the change in kinetic energy when the temperature of an object increases?
The more an objects kinetic energy increases the more it's temperature increases. An object that is traveling at 30 miles per hour will have a higher temperature than an object traveling at 10 miles per hour. This is in part due to friction. Mostly however, it is due to the fact that kinetic energy excites atoms in the object raising the objects temperature. You could put it like this: temperature = energy + atoms. Hope this helps.
What is the kinetic energy of a 30 gram bullet that is traveling at 200 m s?
Kinetic energy = 0.5.m.v2 unit m = mass [=] kg v = velocity [=] m/s Gryazev-Shipunov GSh-30-2 firing 30 × 165mm bullet, bullet mass is 0.4 kg with velocity of 880 m/s Help your self press the calculator for the kinetic energy. Unit calculate is in Joules
How do you calculate the gain of Kinetic Energy?
You calculate the new kinetic energy, you calculate the old kinetic energy, then you subtract.
What type of energy is kinetic and potential?
Kinetic and potential energy are types of mechanical energy.
What energy is in a traveling bullet?
kinetic energy
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.
When a bullet is fired from a rifle does the bullet have a greater momentum and kinetic energy than the rifle?
The momenta of the rifle and the bullet are equal and opposite. The bullet has greater kinetic energy than the rifle.
What a example of kinetic energy?
A bullet racing by a non moving observer has kinetic energy.
How can you use kinetic in a sentence?
A speeding bullet has a ton of kinetic energy.
What is a example of kinetic?
A bullet racing by a non moving observer has kinetic energy.
What type of energy is produced from a speeding bullet?
Kinetic energy and sound energy.
When bullet penetrates into bag of sand what type of energy it exert?
The kinetic energy of the speeding bullet is converted to heat and sound energy.
What affects a bullet's effectiveness its surface area or kinetic energy?
A high kinetic energy, combined with a small cross section.
What type of energy a car is traveling 45 mph have?
Kinetic Energy
What is the kinetic energy of a 22500 lb truck traveling 55 mph?
The kinetic energy of a 22500 lb truck traveling 55 mph is 1/2mv2 is 3084.808kJ.
Can kinetic energy be measured?
Kinetic energy can be measured, but the act of measuring it changes the kinetic energy of the object you are measuring. For example, you can measure the kinetic energy of a bullet fired from a gun by allowing the bullet to strike an known object and then measure the deflection/deformation of the target object. While it is possible to measure the kinetic energy of the bullet this way, the bullet itself is no longer moving after this measurement, and therefore your measurement caused a change in the bullet's kinetic energy. . Kinetic energy (E) can be calculated without changing the kinetic energy of the object under observation if you know the mass (m) of the object and if you can observe or calculate its velocity (v) using the equation E=(1/2)m/v2.
