A car has a kinetic energy of 2000 joules If the speed doubles its kinetic energy will?
It will be 8000 joules. ( if the velocity of a car has been doubled, the KE will be quadrupled. Because the KE is directly proportional to the velocity squared.)KE= 1/2 m v2
What is the kinetic energy of an object that has a mass of 20kilograms and a speed of 2.8?
I believe it would be an application of E=mc2 except instead of c which is the speed of light we use v which is the speed of the car. so E will be KE in this case m will be 2000kg and v = 20 ms. KE=mv2 KE=(2000 kg)(20m/s)^2 KE=(2000 kg) (400 m2/s2) KE = (800, 000 J) or 800 kJ
What happened to kinetic energy if the magnitude is being halved?
Kinetic energy = 1/2 M V2 .Double the mass . . . doubles the KE.Cut the speed in half . . . reduces the KE to 1/4 .Do both . . . reduces the KE to 1/2 its original value.
How much kenetic energy does a 1kg ball have?
KE=1/2MV^2 Or in other words, Kinetic Energy = 0.5 x Mass (1000g) x Velocity (measured in metres per second) Squared (make sure you only square the Velocity) For example if your 1kg ball was going at 2 metres per second, then the equation would look like this: KE = 0.5 x 1000 x 4 = 2000 Joules
Is a match chemical energy?
yes it does It contains approximately 2000 joules (2 kJ) of energy

What is kinetic energy of a 2000-kg car moving at 20 ms?
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
What is A 2000 kg car is moving at 20 ms. What is the kinetic energy?
40,000 j
What has more kinetic energy a mass of 200 grams or a mass of 2000 grams or a mass of 20000 grams?
Assuming all have equal velocity the greater mass (20000g) will have the greater kinetic energy.
What is its kinetic energy when a 2000 kg car moving at twenty miles?
The answer will depend on the rate. 20 miles per day? per hour?
What is the kinetic energy of a 2000 kg car that is moving at 50 km per hour?
Kinetic energy = (1/2) (mass) (speed)2KE = (1/2) (2,000) [ (50 km/hr) x (1,000 m/km) / (3,600 sec/hr) ]2= (1,000) (192.9) = 192,901.2 joules (rounded)
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
When was The Traveling Vampire Show created?
The Traveling Vampire Show was created in 2000-05.
What is the kinetic energy of a 2000kg car moving at 50 mph?
The formula for calculate the energy with in a moving object is :1/2mv.v solution:m=2000 kg v=70 m/h = 70 x 1609.3 m/hr = 112649 m/hr = 112649 / 3600 m/s = 31.3 ms-1 energy=1/2 x 2000 x 31.32 Js-1 = 979690 J = 979.69 kJ
What factors affect and objets kinetic energy?
Its mass and its speed. The kinetic energy formula is ½mv2 (superscript font needs fixing). So a 2-ton car moving at 30 metres per second has a KE of ½ x 2000 x 302 (font needs fixing) joules, in other words 1000 x 900 joules or 900,000 joules.
What will the stopping distance be for a 2000 kg car if -2000 n of force are applied when the car is traveling 20 ms?
200 m
What will the stopping distance be for a 2000-kg car if -2000 N of force are applied when the car is traveling 20 ms?
