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.
392 56 x 7 = 392
√392 ~= 19.799
Yes. 19.7989 is the square root of 392. But 392 is not a perfect square.
The LCM is 392.
The weight of an object is the force exerted on it due to gravity. On Earth, the weight of an object can be calculated by multiplying its mass by the acceleration due to gravity (9.8 m/s^2). Therefore, an object with a mass of 40 kg would weigh approximately 392 N on Earth.
The 40kg student's force (weight) on Earth is about 392.28 newtons. (Force = mass x acceleration). Earth's acceleration is 9.807 meters per second squared.
What planet are you on? I don't mean to be a wise-ass, but weight depends upon the acceleration of gravity, which is different on different planets, whereas mass is the same no matter where you are. On the surface of the Earth, the acceleration due to gravity is 9.8 m/s2, so a 40-kg mass will weigh 40 x 9.8 = 392 newtons.
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 lift a mass of 40 kilograms on Earth, you would need to exert a force equal to the weight of that mass, which is approximately 392 newtons (9.8 m/s^2 * 40 kg). This is due to Earth's gravitational pull on the mass.
