We have to suppose that the 51 Newtons is the only force acting on the mass in question.
F = m A
A = F / m = 51/17 = 3 meters per second2
V = A t = (3 x 5) = 15 meters per second.
Buoyancy = weight of displaced fluid. 10 newtons = 9.8 kilograms with 1G of force applied in a vacuum.
73 kilograms x 9.8 newtons per kilogram (gravity pulling down on the surface of the earth) = 715.4 newtons +++ You cannot convert units of mass into unit of force. The question is based on a misunderstanding, but as the first answer hints, the force applied by a 73kg mass is 715.4N only on Earth. It will be about 112N on the Moon, roughly.
On earth, 980N is 100 kilograms.
6.12kg (mass = Force(newtons) / 9.8)
The question does not make sense. 10 Newtons is a force of 10 Newtons, sufficient to accelerate a mass of 10 kilograms by 1 meter per second squared. The concept of "safe" as applied to a force has no meaning in the context of this question. Please restate the question.
What is acceleration
100 newtons = 10.2 kilograms
Buoyancy = weight of displaced fluid. 10 newtons = 9.8 kilograms with 1G of force applied in a vacuum.
Acceleration is 2m/s^2
There are 9806.65002864 Newtons in 1000 kilograms. Hope this helps!
Multiply mass in kilograms by 9.81 to get weight in Newtons
The mass of 19.6 Newtons is 1.99 kilograms at the earth's surface.
On earth, a mass of 2.26 kilograms weighs 22.15 newtons. (rounded)
45 newtons is about 4.6kg
73 kilograms x 9.8 newtons per kilogram (gravity pulling down on the surface of the earth) = 715.4 newtons +++ You cannot convert units of mass into unit of force. The question is based on a misunderstanding, but as the first answer hints, the force applied by a 73kg mass is 715.4N only on Earth. It will be about 112N on the Moon, roughly.
On earth, 1kg is 9.8 newtons.
On earth, two newtons is 0.204kg
