How much force is needed to accelerate your body at a rate of 2 m sĀ² if you weigh 45 kg?

From Newton's second law, F=m*a (net force is the product of mass and acceleration).
The mass here is 45 kg, and the acceleration is 2m/s2.
Multiply the two together.

ā 7y agoIt is not possible to answer the question because weight is not measured in k but in Newtons. So, it is not clear whether the mass is 45 kg or it is 45 newtons.

What is necessary force wise to accelerate a system?
The total input force in a given direction should be positive. (e.g. You have to overcome friction) Then by Newtons law of motion: F =ma or a =m / F which will cause a body to accelerate.
What force is required to accelerate a body with a mass of 15 kilograms at an 8 meters per secound?
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.
What causes a g force?
g force is the force exerted on a body in the opposite direction to which said body is accelerating. if you're on a rollercoaster and your going not too fast and you suddenly change direction and accelerate quickly, you get pushed back into your seat. g force gets its name as 1g is the equivilent of the force of gravity on the earths surface. That's why when individuals experience g forces greater than 1 or 2, they experience a heavy, weighty feeling and do indeed for a brief moment weigh heavier.Sudden Change In Direction
The force that opposes the motion of an object?
Gravity. The inertia of an object will keep it moving until an opposing force stops it.Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
What effect does a force have on an object in motion?
This depends on in which direction the force is being applied. If the force is applied against the direction of movement, it will slow a body down If the force is applied in the same direction of movement then it will cause the body to accelerate. If the force is applied in a direction at angle to the motion, the force can either cause the object to slow down or accelerate depending on the angle.
How much force is needed to accelerate your body at a rate of 2 if you weigh 45 kg?
90 n is needed to accelerate your body at a rate of 2 if you weigh 45 kg.
How much force is needed to accelerate your body at a rate of 2 ms2 if you weigh 45 kg?
90 N
How much force is needed to accelerate your body at a rate of 2 ms2 if you weigh 45kg?
Force = mass x acceleration. I'll let you do the math.
When can an object have Acceleration?
Whenever there is a resultant force acting on a body which is having some mass, then that body will accelerate (or) A body whose velocity is changing with respect to time and having some mass then the body will accelerate.
How much force is needed to accelerate your body at a rate of 2 m per s per s if you weigh 45 kg?
F = ma. F = 45 x 2 = 90 N.
Is an unbalanced force needed to start motion?
Yes, in order for an object to accelerate or decelerate, the resultant force cannot be zero.To cause a car to accelerate, the forward force (thrust force/engine force) must be greater than the backwards force (friction force/brake force). When this unbalanced force is achieved, the body will initiate its motion.
When a force is applied to a body in what direction will the body accelerate?
Acceleration is in the same direction as the applied force.
How does the unbalanced force affect the motion of the body?
A unbalanced force causes a body to accelerate. (From Newton's second law)
What does force do to objects?
•An action (transfer of energy) that will accelerate a body in the direction of the applied force.
Conditions in which the body is accelerating?
According to Newton's laws, the conditions in which a body accelerates are only those in which a force is acting upon it. With no force acting upon it, a body would not accelerate. With a force acting upon it, it would accelerate by an amount proportional to the force and inversely proportional to its mass.
Can an object accelarate without friction?
Yes, an object can accelerate without friction. The only thing that is needed to accelerate an object is net force acting on it should not be zero. Then the accleration of body is given by Newton's 2nd Law: F = m*a . For example Rockets in space experience no friction, but they accelerate due to force on them by the exhaust gases.
Why a body moves in a circular motion?
A body will move in circular motion if there is a force to accelerate it towards the center.
