A 10 kg go-cart is moving at a speed of 3 ms what is its energy?

The Kinetic energy (KE) of the go-cart can be calculated through knowing is mass and velocity. KE = 1/2 times both mass and velocity squared. The units are KE in joules, mass in kilograms, and velocity in meters per second. If you round to one significant figure this go-carts KE is 50-joules.

∙ 15y agoThe formula for the kinetic energy is m.v2 / 2, so the kinetic energy of the car would be 10 x 32 / 2 = 45 J. Remember that the SI unit for mass is the kilogram, while for speed it is meters per second, so there is no need for converting the units.

What describes how fast an object is moving and in what dirrection?
The maximum speed of any object is hardly equal to speed of light which is 3*10^8 approximately.
How much work must be done on a 10-kg bicycle to increase its speed from 5 ms to 10 ms?
3000 J
What happens to the amount of energy as you go up the energy pyramid?
Basically only 1/10 of the energy from the previous organism is absorbed into the body of the consumer while the other 9/10 is burned up when used for energy by the previous organism. If there is some grass with 100 energy and it gets eaten by a herbivore, the herbivore only receives 10% of the ORIGINAL energy (so the herbivore will have 10 energy.) The animal that will eat the herbivore will only receive 1 energy from the ORIGINAL energy source. The next consumer of the previous organism will only get 0.1 energy from the ORIGINAL energy source and so on.
A measure of the amount of energy in a wave?
JoulesE = hc/λ, where E is energy in Joules, h is Planck's constant, 6.626 × 10-34 J•s, c is the speed of light, 3.0 x 108 m/s, and λ is wavelength in meters.
What is the wavelength in nm of a photon whose energy is 4.7 x 10-14 J?
First get the wavelength in meters by multiplying Plancks constant (in units of J-sec) times the speed of light (in m/sec) and divided by the energy. Then change to nanometers by multiplying by 1 billion.
A 1kg object is moving at 10 ms to double its kinetic energy its speed should be increased to approximately?
It should be increased to approximately 14 m/s.
An example of kinetic energy?
A 10-ton bus moving along at a speed of 10 metres per second (22½ mph). Its kinetic energy ½mv-squared is 0.5 x 10,000 x 22.5 x 22.5 Joules or 2.531 Megajoules.
Can two people be moving in different speed and have same kinetec energy?
Certainly, because kinetic energy is determined by both mass and speed. If I'm traveling at 1/2 the speed that you are, but I have 4 times as much mass as you have, then our kinetic energies are equal. And for an example in the other direction . . . If my mass is only 1% of yours, but I'm traveling at 10 times your speed, then our kinetic energies are equal. That's how a bullet or a baseball can knock a grown person off his feet. Kinetic Energy = 1/2 (mass) x (speed)2
What is the speed of a car that travels 250 miles in 10 hours?
Speed=distance/time 250/10=25 The car is moving at 25 MPH (Miles Per Hour).
At which speed are continents moving?
1 to 10 cm per year, it is not a continuous motion though.
How much energy is consumed by a moving car and a bicycle moving the same distance?
Technically, an object moving at a constant speed on a flat surface doesn't gain or lose any energy. (Also technically, energy is never 'consumed'; it only changes from one form to another, or gets transfered from one body to another.) If a car and a bicycle both roll down the same ramp, the car has more energy of motion when they reach the bottom. If a car and a bicycle are both standing at a stop light, both take off when the light changes, and both accelerate together to 10 mph, the caruses more energy than the bicycle to get up to the same speed.
Jack can run at 75 meters in 10 seconds how fast is he moving?
Jack is moving at a speed of 7.5 meters per second.
What is the momentum of an object that is moving in a straight line at a speed of 10 ms and has a mass of 10 kilograms?
Simply multiply the velocity times the mass.
What is the momentum of an object that is moving in a straight line at a speed of 10 m s and has a mass of 10 kilograms?
100 Kg-m/s
Is it legal for a 10 year old to ride a go-cart in town in South Dakota?
it is not legal for anyone regardless of age to ride a gocart on any street
What is the mass of a proton moving at a speed of 2370 meters per second?
The mass of such a proton is 1.67262158 × 10-27 kilogram. (Since it's only moving at 0.00079% of the speed of light, its relativistic mass may be ignored.)
Two things moving at 10 km Which one has more kinetic energy?
it is either both or none
