∙ 12y agoDo you want the velocity?
KE = 1/2(mass)(velocity)2
so,
500 Joules = 1/2(10 kg)V2
multiply through by 2
1000 = 10V2
divide both sides by 10
100 = V2
take square root both sides
10 m/s = velocity

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 10-kg dog chasing a car at 5 ms?
The formula for kinetic energy is (1/2) x mass x velocity2. If mass is in kg. and speed in meters per second, the energy will come out in Joule.D. 125 J
What is the kinetic energy in joules of a 850 lb motorcycle moving at 66mph?
Answer= 5703.55 Joules (see below for explanation)So Kinetic energy= 0.5 mv2Unit-wise 1 Joules = 1 kg m2s-2Therefore we need to convert 66mph -1 mph= 1.61 km/h66mph=106.22 km/h= 29.51 m/s =v OR (106.22 x 1000)/(60x60)Also need convert 850lbs to kg-1kg= 2.2 lbs1/2.2 kg = 1 lbTherefore 850 lbs= 1/2.2 x 850= 386.55 kg= mBack to the original equation KE= 1/2 mv2= 0.5 x 386.55 x 29.51= 5703.55 Joules = 5.7 KiloJoules
How much biomass of human can 5000 kg of corn support?

What is the kinetic energy of a 2000 kg bus that is moving at 25m?
kinetic energy is 1/2mv^2, our velocity is 20 m/s , our mass is 2000 kg. Plugging it in you get 1/2 (2000) (400) = 1000 * 400 = 400000 joules
How much energy is 500 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.
What is the potential energy of a 500 N weight before it falls 10 m?
500 n is a force created by a mass (500 / 9.807) = 50.98 kg so: potential energy = m * g * h = 50.98 * 9.807 * 10 = 5000 joules. . if it was 500 kg (not newtons) weight, then m*g*h = 500 * 9.807 * 10 = 49035 joules.
10 KG object travels 500 M space in 25 seconds. How fast is it going?
The 10 KG is a distraction. 500m in 25 seconds = 500/25=20 m per second.
What is the potential energy of an object that has a mass of 40 kg at a height of 17 meters?
The object's potential energy is 6,664 joules.
How many joules of work would be accomplished if you move a 200 kg slug 10 meters?
2000 joules
What is the kinetic energy of an object that has a mass of 20 kg and a speed of 2.8m per second?
The object's kinetic energy is 78.4 joules.
What is the kinetic energy of an object with a mass of 125 kg, moving at 60 m/s?
225,000 Joules
How many joules of potential energy does 10 kg box have that is 1 m from the floor?
This box has potential energy of 98 Joules.
If an engine must do 500 joules of work to pull a 10 kg load up4 meters what is the engine's efficiency?
energy required to lift up 10kg=10x9.81x4=392.4 joule. enegy produced by the engine=500 joule efficiency=392.4/500=78.48%

What force is required to produce an acceleration of 2 m per second square in a body of mass 500 kg?
1000 joules
What is the potential energy of a mass of 500 g raised to a height of 2 m?
The formula for working out Potential enery is: PE = mgh - where g equals to the acceleration due to gravity (which is 10 newtons) - mass should be in Kg's - and height in meters - final answer should be in Joules (J) Therefore substitute it in :-) Pe = (500g = 0.5kg) x (10N or more exact 9.8N) x (2 meters) Pe = 10 Joules of potential energy with a object weighing 500g (or 0.5 kg) and from a height of 2 meters
