If the mass of the barrel is 40 kilograms and the barrel is presently on earth, then it
weighs 392 newtons (88.2 pounds). What you do with it, what dizzying gyrations you
subject it to, or what other objects happen to be nearby, have no effect on its weight.
To calculate the weight of a rolled steel with given dimensions, we need the density of the steel. Assuming a typical density of 7850 kg/m³, the weight can be calculated as follows: the volume of the rolled steel is (π * radius² * height) - (π * (radius - thickness)² * height). Substituting the values, the weight would be (π * (2 feet)² * 12 feet) - (π * (2 feet - 1/4 inch)² * 12 feet), which equals approximately 19,347 pounds.
height * circumference (picture the cylinder cut along the long edge, then rolled out flat, and you would measure height * width) note: if you need to include the circles at the top and bottom of the cylinder, add (circumference / 3.1415926 )^2 * 2 * 3.1415926
It is 1/2 if it is a fair number cube which is rolled once.
It is 1/6.
It is 0.722... recurring.
40 kilograms!
M g H = (40) x (9.8) x (5) = 1,960 newton-meters = 1,960 joules
When a 40-kg load is raised 5 meters, its gravitational potential energy increasesby [ m g h = (40) x (9.8) x (5) ] = 1,960 joules.That's the minimum work required to get it up there, and it doesn't matter how fastor slowly the lift took place, or what route it followed.
Assuming you're on Earth, the barrel weighs 392 N.
Potential energy is calculated as mgh - mass x gravitation x height. The 10 meters are irrelevant in this problem; what is relevant is that the object is elevated 5 m. higher than it was before. Unless otherwise stated, use 9.8, or perhaps 9.82, for the gravitation. This is more or less the standard gravitation on Earth.
That is equivilent to dropping it from a height of 5 meters, about 16 feet, so I would say no but you don't specify the mass or weight of the ball of rolled up paper. A single sheet of paper, rolled up, no, several tons of paper wrapped into a tightly packed ball the size of a tank, yes.
Yes, they can be rolled after being end loaded. When you roll a bat you are rolling the sweet spot not the entire length of the barrel.
To barrel means to move rapidly and recklessly, as if you rolled a barrel down a road. A tin can on wheels would be a description of an automobile.
The magnitude of the balls displacement is 9 meters.
And the question is????
(t)rolled
The potential energy that the box gained only depends on how high it was raised, not on how it got there. If both boxes started at the same height and ended at the same height, then they both gained the same amount of potential energy.
