Want this question answered?
The force required is 15 Newtons.
Gravity (acceleration) is equal to Force divided by mass. So, 126 / 15 = 8.4m/s^2
F = m Awhere . . .F = force acting on the massm = mass of the massA = acceleration of the massF = (2.5) x (6.0)= 15 kg-m/sec2 = 15 newtons
Work = (force) x (distance) = (15) x (5) = 75 joules.The mass of the crate is irrelevant.
F = ma(Force = Mass * Acceleration)F = (3) * (5)F = 15 N(15 Newtons)
Since you don't tell us anything about friction or any other forces in the body's environment, we have to assume that there aren't any, and answer the question for that case. Any force, no matter how small, will accelerate any body, no matter how big. The greater the force is, the greater the acceleration will be. To find out exactly what the acceleration is, simply divide the force by the mass.
The force required is 15 Newtons.
Multiply the force by the distance. The mass is irrelevant for this problem.
Force = mass × acceleration = 5 kg × 3 m/s² = 15 N
Gravity (acceleration) is equal to Force divided by mass. So, 126 / 15 = 8.4m/s^2
F = m Awhere . . .F = force acting on the massm = mass of the massA = acceleration of the massF = (2.5) x (6.0)= 15 kg-m/sec2 = 15 newtons
F=maF= 15 x 10F= 150N
If a force of 20 N acts through a distance of 15 m, then it does (20 x 15) = 300 joules of work.The other facts of the case, such as the mass of the crate being pushed, don't matter.
50 times 500= 2500 m/sec squared.
Force = mass x g, where g is the acceleration due to gravity (-9.8m/s2)To find mass, manipulate the equation such thatmass = Force/g = -147N/-9.8m/s2 = 15kgThe force and g are negative because they act in a downward direction.The mass is in kg because a Newton is a kg*m/s2.
Work = (force) x (distance) = (15) x (5) = 75 joules.The mass of the crate is irrelevant.
F = ma(Force = Mass * Acceleration)F = (3) * (5)F = 15 N(15 Newtons)
