The bike's kinetic energy is 45 joules.
500 joules is equal to 368.78 ft-lbf. For example, an object has 500 joules of kinetic energy, when its mass is 10 kg (~22 lbs) and it is traveling at 10 m/s (36 km/h or ~38.2 ft/s). Second example: The muzzle energy of a traveling 9mm bullet is around 500 joules. Third example: An object with mass of 5kg (11 lbs) and which is raised at 10 metres (32.8 ft) has around 500 joules of potential energy. So, 500 joules is quite much. Getting hit with an object which has 500 joules of kinetic energy can be lethal.
velocity Kinetic energy is equal to (1/2)mv2, where m is mass and v is velocity. Higher velocities contribute even more to higher kinetic energies than higher masses since velocity is squared in the equation. For comparison, a 6.35 kg bowling ball moving at 7.6 m/s will have a kinetic energy of 183.4 Joules. A 0.02 kg bullet moving at 200 m/s will have a kinetic energy of 400 Joules. (Increase that to 300 m/s, and the kinetic energy moves up to 900 Joules.)
A 60 gram bullet fired from a gun with 3150 joules of kinetic energy has a velocity of 324.04 meters per second or 1,063.12 feet per second. (This is about 725mph).
60 grains = 0.003888 kg 3000 feet per second = 914.4 m/s Kinetic Energy = 0.5 x Mass x Velocity^2 KE = 0.5 x 0.003888 x 914.4^2 = 1625.43158784 Joules
The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.

It takes only 80 joules of kinetic energy in a bullet to kill a normal human being if it hits any of the unprotected vital portion of our body.

To measure kinetic energy:Let us suppose an object of mass m moving wtih velocity vKinetic Energy of that object= mv2/2
Dear Wiki Questioner, To calculate the kinetic energy of an object, we use the following equation: KE=(1/2) m v^2 Where KE is the object's kinetic energy in Joules m is the object's mass in kilograms and v is the object's velocity in meters per second So for your question, we first convert the mass of the bullet into kilograms so we can use it in our equation: 25g (1 kg/ 1000 g) = .025 kg The mass of the bullet is .025 kilograms! Now we plug the numbers into the equation and solve: KE = (1/2) .025 kg (500 m/s)^2 = 3125 kg m^2/s^2 = 3125 J So the kinetic energy of your bullet is 3125 Joules
