## How long will it take a 2.5 KW motor to lift a 80 kg block 30 m high?

Motor will take 9.4 s to lift block.

Work done by motor to lift block is equal to change in gravitational potential energy of block..

## How much is 1kg force?

On Earth, an object with a mass of 1kg will experience a force of 10N due to gravity, i.e. the weight of a 1kg mass is 10N.

## How much force is required to lift a 100g mass?

Answer. 0.98 (force).

## How many watts does it take to lift 1kg?

10 WattsIf you can keep lifting a 1 kg weight to a height of 1 meter every second, weight after weight after weight, then you will be steadily producing 10 Watts of power.

## How much work is done on a 300 Newton suitcase to lift it 0.50 meter?

1 Answer. Work done is force multiplied by distance, Hence work done is 300×0.50=150 joules.

## What is the force of 100g?

Force of Earth gravity acting on a gram….Please share if you found this tool useful:Conversions Table2 Grams-force to Newtons = 0.019680 Grams-force to Newtons = 0.78453 Grams-force to Newtons = 0.029490 Grams-force to Newtons = 0.88264 Grams-force to Newtons = 0.0392100 Grams-force to Newtons = 0.980712 more rows

## How far will 350 J raise a 7 kg mass?

7kg of mass weighs 70N. 350J = 350 Nm^-1. => distance moved = (350/70)m = 5m. answered by: lily S.

## How much force is required to lift a mass of 1kg?

So to lift this 1kg mass will take more than 9.8 N. 10 newtons of life would create a net force of 0.2 N so 0.2/1 = 0.2 meters acceleration. Note that, gravitational force is one side of the same coin, with acceleration on the other.

## How much work is required to lift a 2 kg mass to a height of 10 meters?

Answer. Answer: the Work done to life the mass of 2 kg to a height of 10 m is 196 J.

## How much force is needed to lift an object with a mass of 200 kg?

Kg MpsE2 is equal to 1 Newton and it is denoted by N. This way the force required to lift the object of mass 200 g is 2N.

## How much energy does it take to lift 1kg 1m?

On earth it takes about 10 Newton-meters (N-m) of energy to raise a 1 kilogram mass to a height of 1 meter. Since 1 N-m equals 1 Joule, that’s 10 Joules. If it takes 1 second to lift the weight 1 meter, than you have converted 10 Joules of energy to potential energy in one second. That’s 10 Watts of power.

## What is the unit of force?

NewtonForce/SI units

## How much energy does it take to lift 1 ton?

Assuming you mean a tonne – ie a metric tonne, 1000kg – the energy required to lift one tonne to a height of one meter is given by the equation ‘mgh’ – mass times the acceleration due to gravity times the height, so that’s 1000 * 9.8 * 1, or 9,800 Joules.

## How much force is needed to lift a person?

Yes, lift is nothing but the force in the upward direction. So to keep a 150 pound person aloft, you need a lift of 150 pounds (150 pound-force).

## How much power is required to lift a body of 50kg?

So, the body will posses 4900 joules of energy. It is the required solution.

## How do you calculate the force required to lift an object?

If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh. We define this to be the gravitational potential energy (PEg) put into (or gained by) the object-Earth system.

## What is the largest unit of force?

One newtonOne newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 pound in the foot-pound-second (English, or customary) system.

## How much force is needed to lift the 10Kg weight?

5 Kg forceHow much force is needed to lift the 10Kg weight? The correct answer is (B) 5 Kg. In a double-pulley system, the force is equal to the weight divided by two. It will require a 5 Kg force to lift a 10Kg weight.

## What is the minimum force required to lift an object?

Because the surface on which the object is at rest, is already providing a normal force to the object which is equal to mg. g=9.8N/kg or 9.8m/s^2. … According to textbook, PE=mgh because minimum force required to lift the object is mg and height is h.

## How much force is required to lift the weights?

The force varies by less than 1%. So the force needed is the mass times acceleration of gravity. This is 9.8 m/s/s, so force is 9.8 newtons as a newton is defined to be a kg m/s/s. You can convert it to pounds: it’s 2.205 pounds.

## Who discovered that all objects fall at same velocity?

Galileo GalileiThe remarkable observation that all free falling objects fall with the same acceleration was first proposed by Galileo Galilei nearly 400 years ago. Galileo conducted experiments using a ball on an inclined plane to determine the relationship between the time and distance traveled.
