How much power is required to lift a body of mass 50 kg to a height of 120?

The body will posses 4900 joules of energy.

How do you calculate power to lift?

Let us calculate the work done in lifting an object of mass m through a height h. 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.

How much power is needed to lift a weight?

Lifting Weights: 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.

What is the average power required to lift a mass of 100 kg to a height of 50m in 50 seconds?

P=mght=100×9.8×5050=980J/s.

What power is needed to lift a 50-kg person a vertical?

W = ~1000 N (Note: The weight of a 50-kg object is approximately 500 N; it takes 500 N to lift the object up.)

How much energy would be created from a mass of 50-kg?

The amount of potential energy is dependent upon mass and height and is found using the equation PE=m*g*h where g is the acceleration of gravity (approximated here to be 10 m/s/s). For a 50-kg sledder on top of a 4.0-meter high hill, the potential energy is 2000 Joules.

How much electricity does lift use?

The amount of energy is rather small. Even assuming on the high side, say 10 horsepower, that’s 7,500 watts. In one hour that’s 7.5 kilowatt-hours, about 70 cents. To lift you one floor, say one second, that would be 1/3,600th of that, about 2 watt-hours, about 0.02 of a cent.

What is the average power required for first 30 sec?

Answer: your answer is 103 kg.

How do you calculate the power required to lift 100 kg?

power = work/time. work = force x distance. So power = force x distance/time or equivalently, power = force x speed of lifting (rate) Force needed to hold 100 kg against gravity = 100*9.8, rounding it up to 1000N.

How many Watts Does It take to lift 10 kg?

It depends upon speed of lifting. Force required for lifting 10 kg weight is (10*9.81=) 98.1 Newton. If you assume lifting speed to be 0.1 meter / sec, then power required is (98.1 * 0.1 =) 9.81 Watt. This much power is required without considering losses in lifting mechanism.

How much power does it take to lift a heavy object?

If you assume lifting speed to be 0.1 meter / sec, then power required is (98.1 * 0.1 =) 9.81 Watt. This much power is required without considering losses in lifting mechanism. Generally rated motor speed is 1500 rpm. Consider a simple lifting arrangement consisting of a rope and pulley.

How much torque is required to lift a 10 kg weight?

Since the torque available is 60 kg cm, the weights that can be lifted are 60 kg and 30 kg respectively. How much power is required to lift a 10 kg weight by a DC motor? It depends upon speed of lifting. Force required for lifting 10 kg weight is (10*9.81=) 98.1 Newton.
