What force in newtons is needed to accelerate a 2kg mass at 7 ms squared?
acceleration...
What force is necessary to accelerate a 70-kg object at a rate of 4.2 ms?
Force = mass x acceleration = 70 x 4.2 = 294 Newtons
How much force ( in newtons ) does a baseball pitcher have to exert on a 250g baseball to make it accelerate to 50 ms the instant that leaves his hand?
?
What are newtons?
Newtons are a unit of force. A force of 1 Newton acting on a mass of 1 kilogram causes it to accelerate by 1 metre/second every second by Newton second law: force = mass x acceleration. A 1-kg mass that is dropped will accelerate down at 9.81 metres per second per second before it hits the floor, therefore the force acting it, which is its weight, is 9.81 Newtons. But the same 1-kg mass, on the Moon, accelerates one sixth as fast, and its weight is less, one sixth of the old weight, so its weight is only 1.63 Newtons.
A Net Force of 10 N causes an object to accelerate at 2 ms What is the mass of the object?
F = m A10 = 2 mm = 5 kg
Can a stationary object have a mass 12 kilograms and weight of 12 newtons?
If it is placed at a point where the force of gravity is such that it would accelerate the body at 1 ms-2.
A small engine causes a 0.30 kg model airplane to accelerate at a rate of 11ms2 What is the net force on a model airplane?
3.3kg ms/^2 0.3kg * 11 m/s^2 = 3.3kg ms/^2
What unbalanced force is required to accelerate a 1500 kg race car at 3.0 meters per second squared?
Force = Mass*Accerelation = 1500 kg*3.0 ms-2 = 4500 Newtons
What force is necessary to accelerate a 70 kilogram object at a rate of 4.2 m's?
F=ma, so=70*4.2=294NAnd acceleration has units of ms-2
Calculate the force it would take to accelerate a 250 kg motorcycle at a rate of 5 ms to the second power?
F = m A = (250) (5) = 1,250 newtons
What force is necessary to accelerate a 70 kg object at a rate of 4.2 ms squared?
70 kg x4.2 m/s 140 +2800 294.0 m/s
The acceleration of an object varies directly as the force acting on it If a force of 240 newtons causes an acceleration of 150 ms². what force will cause an acceleration of 100 ms2?
240N causes= 150a xN causes= 100a X= 240*100\150 = 160N
