How do you calculate the kinetic energy of a 3 kg toy cart that moves at 4 miles per second?
4 miles per second = 6437.4 metres per second.
So kinetic energy = 0.5*3*6437.42 Joules = 62.16 mega Joules (approx).
I suspect the questioner actually meant 4 metres/second but has muddled two systems of dimensions that are not compatible anyway!
That would give a rather more probable 0.5 * 3 * 42 = 24 Joules.
Are we doing someone's homework again ....? Sometimes I think the better answer is to set any mixed-up units straight and just quote the formula! They'd learn more!
What else can I help you with?
Would a scooter that is going 10 miles per hour have more kinetic energy or less than a motorcycle going at the same speed?
less
How do you convert a rate of y miles per hour to x miles per second?
y miles per hour = y/60 miles per minute (60 minutes per hour) y/60 miles per minute = (y/60)/60 miles per second Take y, the number of miles traveled per hour, and divide by 3600 to get the amount of miles per second. Example: 100 miles per hour --> miles per second 100/3600 = 1/36 1/36 miles per second
How do you calculate a tip?
Add all your miles up.
Conversion formula for kph to miles per second?
Formula: kph x 0.000172603109 = miles per second.
What is the equivalent value of 15 kilometer per hour in miles per second?
0.0026 miles per second.
Which has the most kinetic energy a 1000 kg car traveling 30 ms or a car traveling 45 ms?
WOW, 5 MILES PER SECOND. I guess that I would have to calculate the miles per hour. To do this, we must multiply 5 miles per second times 3600(the number of seconds in an hour). That is 18000 miles per hour. I like to work in the SI system, so by converting this to meters per second, we get 8.04672E3 meters per second. Kinetic energy is defined as one half mvsquared. The Kinetic Energy is equal to 3.2374E10 Joules.
How much kinetic energy does a runner have when dashing at 7 miles per second?
7 miles per second? Don't you mean 7 meters per second?
What is the kinetic energy of a 5 kg cat chasing a mouse across the yard at 2 miles per second?
kinetic energy = 1/2 * mass *(velocity)^2 = 1/2 * 5 * 2 * 2 = 10 joules
How many joules of kinetic energy does a 750 kg car traveling at 65 mi hr have. By what factor would its kinetic energy decreases if the car travel half as fast?
For this question, we will use the formula K = 1\2 mv2. But first, we must convert the 65 miles per hour into meters per second. Multiply miles per hour by a factor of 1.609 to get kilometers per hour. Divide this answer by 3600 to get kilometers per second. Multiply this by 1000 to get meters per second. In this case, the velocity in meters per second is aproxamitely 29 meters per second. To get the kinetic energy, we multiply one half, times the mass 750 kg, times 292 meters per second. This yields 315375 Joules. If we halved the velocity, the kinetic energy would be one-fourth that of the original kinetic energy. This is because the velocity is squared. This holds true if we go to one third the original speed. Then it would be one-ninth of the original kinetic energy.
What is the kinetic energy of a particle weighing 175 lb and traveling at 60 mph?
To calculate kinetic energy, first convert pounds to kilograms (1 lb = 0.453592 kg) and miles per hour to meters per second (1 mph ≈ 0.44704 m/s). Then, use the formula KE = 0.5 * mass * velocity^2 to find the kinetic energy. Substituting the mass and velocity values, you can calculate the kinetic energy in joules.
What would the kinetic energy of a rock sitting on the ground be?
Zero. You need to think in terms of "frame of reference" as in what are you comparing the rock to. If you are an observer sitting next to the rock then the kinetic energy of the rock RELATIVE TO YOU is zero - I.E. the rock isn't moving relative to you and thus has no kinetic energy - energy of motion - relative to you. If you are an observer sitting a million miles from earth watching the rock then it is zipping around at 1000 miles per hour as the earth spins on its axis and it has significant kinetic energy RELATIVE TO YOU.

What is a car's kinetic energy if it is 1500 kilograms and is moving at a speed of ten miles per second?
Are you sure you mean 10 miles per second? That is a speed of 36,000 mph (unless you are referring to the speed of the car relative to the orbit of the earth as the earth orbits the sun, but that is approx 19 miles per second). I think you mean 10 metres per second (as you've used a metric measure for the mass of the car). kinetic energy = ½ × mass × velocity² → KE = ½ × 1500 kg × (10 m/s)² → KE = 75000 kgm²/s² = 75000 Joules = 75 kJ
What is the kinetic energy in joules of a 0.02 kg bullet traveling 300 miles per second?
The kinetic energy of the bullet can be calculated using the formula: KE = 0.5 * m * v^2, where m is the mass and v is the velocity. Plugging in the values, KE = 0.5 * 0.02 kg * (300 m/s)^2 = 900 J. So, the kinetic energy of the bullet is 900 joules.
What has the most mechanical kinetic energy?
a car going 60 miles per hour
Why does a small asteroid make such a large impact on earths surface?
It's because of the asteroid's kinetic energy. Think of it like this. Even though an asteroid can be relatively small (10 meters across), it moves at an average speed of 25 kilometers per second, or about 15.5342798 miles per second. Now, that alone might not seem like much. However, once you calculate the kinetic energy, or the collision energy in this case, you'll see why. The "average" asteroid is about 10 km across with a mass of 1.47 x 10^21 kg. So, after figuring it's kinetic energy, (1/2)mv^2, we find it has a collision energy of 9.1875x10^27 joules, equal to 109,375,000,000,000 of the atomic bombs dropped on Nagasaki.
What energy transformation is it when a driver fills his car with gas then drives three hundred miles?
The major conversions are chemical energy in the fuel to heat energy in the cylinders to kinetic energy of the car. Other changes involved include chemical energy in the driver's food to kinetic energy in his muscles to operate the pump, and electrical energy in the pump to kinetic energy of the fuel as it flows into the car.
