# How much net force is a 2 kg object moving horizontally with a speed of 4m s?

## How much net force is a 2 kg object moving horizontally with a speed of 4m s?

Answer and Explanation: Thus, if an object is moving with constant velocity and no external force, like a frictional force, then the object continues to move with the same velocity in the same direction. Hence the net force required is ZERO.

## What is the force required to move a mass of 1 kg at rest on a horizontal of plane?

=0.1×1×9.8=0.98N.

## What is the formula for net force with mass?

Newton’s second law of motion states that F = ma, or net force is equal to mass times acceleration.

## What is the force acting on an object of mass 17 kg is moving with a uniform velocity of 22 Metre per second?

If it is moving with uniform velocity 22 m/s, then the resultant force must be zero. But if it is moving with some acceleration or deacceleration, i.e. change of velocity then some net force must exist. Hence Force acting is 0N.

## What is the force required to move a body of mass 1000 kg?

Answer: The force required to move a body of mass 1000kg is 4000 N. The force required to move a body is F = μmg, where μ is the coefficient of friction, m is the mass of the body and g is gravity. hence, the force required to move 1000 kg if the coefficient of friction is 0.4 will be 4000N.

## How much force is required by a car of mass 1000 kg starting from rest to gain a velocity of 30 metre per second?

Thus, force required is 4500 N.

## What is the horizontal motion formula?

(b) The equation that describes the horizontal motion is x=x0+vxt. x = x 0 + v x t . With x0=0, x 0 = 0 , this equation becomes x=vxt.

## What are the 3 formulas for force?

• a = v/t.
• F = mv/t.
• F = p/t = dp/dt.

## What is SI unit for force?

The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m.

## What is the symbol for net force?

The net force can be calculated using Newton’s second law, which states that F = ma, where: F is the net force. m is the mass of the object. a is acceleration.

## How do you calculate mass?

The first formula of mass is expressed as, Mass = Density × Volume. This means if we know the density and volume of an object, we can find its mass using this formula of mass. The second formula of mass is expressed as, Mass = Force ÷ Acceleration.

## How do I solve for net force?

Fg = gravitational force. When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, FNet = Fa + Fg + Ff + FN.

## When a force of 4 N acts on a mass of 2 kg for a time of 2 sec What is the rate of change?

Data: Force= 4 N, Mass= 2 Kg, Time= 2 Sec. Rate of change of momentum is Force = ? V= F×s/m=4×2/2=8/2=4. F= m×v/s=2×4/2=8/2=4.

## How much net force is required to accelerate a 1000kg car at 4m s 2?

So the net force is required to accelerate a 1000 kg car at 4.00 m/s2 is 4000 N.

## What is a mass of 10kg moves with a velocity of 4m?

∴ Kinetic energy = 80 J and momentum = 40 kgms−1. Q. A body of mass 10 kg is moving with velocity 4 m/s. If P is the momentum associated with the body and K.E. is the kinetic energy.
