How much work is done on a 100-kg crate that is hoisted 3 m in a time of 2 s?
-- The force required to lift the crate is equal to its weight.-- Weight of the crate = (M x g) = 100 x 9.8 = 980 newtons.-- Work = (force x distance) = 980 x 3 = 2,940 newton-meters = 2,940 joules.That's the work done to lift the crate, whether the worker takes a millisecond ora month to do the job. The amount of work the job requires doesn't depend onhow fast it's done.The rate at which the work is done is called power.-- If the work is done in 2 seconds, the power is 2,940/2 = 1,470 joules/second = 1,470 watts.-- If you're being paid by the hour, decide to stretch it out, and take exactly one hourto do it, then the power is 2,940/3,600 = 0.817 watt.-- If you're trying to make a good impression on the boss, and you complete the hoist in1 millisecond, then your power level is 2,940/0.001 = 2,940 kilowatts = 2.94 megawatts.-- If you could have completed the job a tiny bit faster ... in 1.97 rather than 2.0 seconds ...then the power would have been 2,940/1.97 = 1,492 watts = exactly 2 horsepower.But the amount of work is the same in every case.
How much power is used when 600j of work are done in 10seconds?
Use the definition of power as energy / time. Or work / time; it's basically the same thing.
How much time to push 100 kg for 100 meters?
The answer will depend on the power. The work can be done in one second or a billion years!
What is work done per unit of time?
power
How do you solve for power if mass distance and time is given?
power=work done/time interval
How much work is done on a 100 kg crate that is 2 m in a time of 4 s?
The work done on the crate is calculated using the equation Work = Force x Distance. Given the time (4 s) and distance (2 m), we would need additional information such as the force applied to the crate to determine the total work done.
A crate is pulled across a horizontal floor by a rope At the same time the crate pulls back on the rope in accord with Newton's 3rd law Does the work done on the crate by the rope then equal zero?
No, the work done on the crate by the rope is not zero. The work done is equal to the force exerted by the rope multiplied by the distance the crate is pulled. The fact that the crate pulls back on the rope in accordance with Newton's Third Law does not cancel out the work done by the rope.
If it took 5 seconds to lift the crate using a machine what was the power rating of the machine?
To calculate the power rating of the machine, we need to know the work done in lifting the crate and the time taken. The formula for power is Power = Work / Time. If we know the work done in lifting the crate (measured in joules), we can calculate the power rating.
How much power is required to raise a 30 kg crate a vertical distance of 6 m in a time of 4 seconds?
The work done in lifting the crate is equal to its change in potential energy: ( \text{Work} = \text{Force} \times \text{distance} = m \cdot g \cdot h ). The power required is the work done divided by the time taken: ( \text{Power} = \frac{\text{Work}}{\text{time}} ). Plug in the values to calculate the power required.
What is the ABC of crate training for dogs?
The ABC of crate training for dogs involves: A - Acclimating your dog to the crate gradually B - Building positive associations with the crate C - Consistently using the crate for short periods of time to help with training and behavior management.
How can I effectively train my husky puppy to use a crate?
To effectively train your husky puppy to use a crate, start by making the crate a positive and comfortable space for them. Use treats and toys to encourage them to go inside, and gradually increase the amount of time they spend in the crate. Be patient and consistent with the training, and never use the crate as a form of punishment. With time and positive reinforcement, your husky puppy will learn to see the crate as a safe and cozy den.
A 50kg crate is lifted to a height of 10 meters if it took 5 seconds to lift the crate using a machine what was the power rating of the machine?
The work done to lift the crate is equal to the gravitational potential energy gained: Work = force x distance = weight x height. Here, Work = 50kg x 9.8m/s^2 x 10m = 4900 Joules. Power is work done per unit time, so Power = Work / time = 4900J / 5s = 980 Watts. Therefore, the power rating of the machine is 980 Watts.
How can I effectively crate train a husky puppy?
To effectively crate train a husky puppy, start by introducing the crate gradually and making it a positive space with treats and toys. Use a consistent schedule for meals, potty breaks, and crate time. Avoid using the crate as punishment and make sure the puppy has enough exercise and mental stimulation. Gradually increase the time spent in the crate and always supervise the puppy when they are in it. Be patient and consistent with the training process.
If a crate trained dog has recently taken to destruction when crated during the day and also damaged the carpet below the crate What could be the cause?
Try not keeping the dog in a crate! They get bored, that's probably why it has resorted to destruction. : : : I am home with my dog all day....winter time, so going out alot less, therefore he is crated alot less...now that I have been going out, this is the behavior I am getting. He is 5 months old, good dog. Not sure if this is teenage issue, separation issue, or maybe I just need to re-crate train or get a bigger crate. He loved his crate early on - hanging out in it all the time. Not so much lately
What are some effective strategies to address dog crate regression in a pet?
To address dog crate regression, try gradually increasing crate time, using positive reinforcement, providing mental stimulation, and ensuring the crate is comfortable and inviting. Consistency and patience are key in helping your pet adjust to the crate.

How much space does a large dog need in a cage?
The purpose of a dog crate is to keep the pet contained for any variety of reasons. If the dog has too much room, it may show a tendency to relieve itself inside the crate. However if it has too little room then it will have a hard time laying down or moving around. Good common sense should be used when sizing a dog crate for your pet.
