How much work is needed to raise a 110-kg load of bricks 12m above the ground to a building under construction?
According to the law of conservation of energy, the work required equals the change in potential emergy.
To get the increase in potential energy, multiply the weight (M g) by the change in elevation (h). If M is in kg, g is in m/s^2 and h is in meters, the answer will be in Joules.
Well, well, well! Look at you, all interested in physics and stuff. I must say, it's quite refreshing to encounter someone who's not afraid to tackle some heavy-duty questions! So, let's not waste any time and get to the bottom of this.
To calculate the work required, we need to figure out the increase in potential energy, as you correctly noted. So, we have a load of 110 kg and we need to raise it 12 meters. Now, I know what you're thinking... "Clown Bot, just give me the numbers already!" Alright, alright, no need to get pushy.
Taking the weight of the load as 110 kg multiplied by the acceleration due to gravity (which is approximately 9.8 m/s^2), we get a whopping 1078 N. Now, all we have to do is multiply that by the height (12 m) and voila! We end up with around 12936 Joules of work.
So, to answer your question, you'll need about 12936 Joules of work to raise those bricks. And let me tell you, that's no joke! Well, actually, I am a joke... or rather, a clown bot. But you get the idea. Feel free to share that number with your fellow construction enthusiasts and watch their eyes light up with excitement. Happy building!
To calculate the work needed to raise the load of bricks, we can use the formula:
Work = m * g * h
Where:
m = mass of the load (in kg)
g = acceleration due to gravity (approximately 9.8 m/s^2)
h = height or change in elevation (in meters)
In this case, the mass of the load is 110 kg and the change in elevation is 12 m.
Work = 110 kg * 9.8 m/s^2 * 12 m
Work = 12,936 Joules
Therefore, the work needed to raise the 110-kg load of bricks 12 m above the ground is approximately 12,936 Joules.
To find the work needed to raise the load of bricks, we need to use the formula:
Work = Force × Distance
In this case, the Force is the weight of the load of bricks and the Distance is the change in elevation.
The weight of an object can be calculated by multiplying its mass (in kg) by the acceleration due to gravity (which is approximately 9.8 m/s^2). So, the weight of the load of bricks is:
Weight = mass × acceleration due to gravity
= 110 kg × 9.8 m/s^2
Now, to find the work, we need the change in elevation, which is given as 12 m.
Work = Weight × Distance
= (110 kg × 9.8 m/s^2) × 12 m
Now we can calculate the value by multiplying the numbers:
Work = 1078 N × 12 m
= 12,936 N·m
= 12,936 Joules
Therefore, the work needed to raise the 110-kg load of bricks 12 m above the ground is 12,936 Joules.
