What is the GPE of a 3 kg block 10 m above the floor?

GPE = m*g*h = 294 Joules.


How many kilograms is 294 pounds?

The answer is 133.356 kg (approx.). Kilogram is the SI unit of mass and pound is an imperial unit of mass. To convert from pound to kg, multiply the pound unit by 0.453592.294 pounds = 133.356 kilograms or 133 kilograms 356.157 grams1 pound ~= 0.45359 kilograms1 kilogram ~= 2.2046 pounds


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


What is the potential energy of a book with mass of 2 kg and a height of 15 meters use pemgh?

The potential energy of the book can be calculated using the formula PE = mgh, where m is the mass (2 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height (15 m). Plugging in these values, we get PE = 2 kg * 9.8 m/s^2 * 15 m = 294 Joules.

The density of beryllium 1,850 kg/m³ or 1.85 g/cm³. The SI density standard is kg/m³.


What are 30 newtons equal to?

30 newtons is equivalent to the force required to accelerate a 1-kilogram mass at a rate of 30 meters per second squared.


An object has a mass of 180 kg on the moon What is the force of gravity acting on the?

The force of gravity on the moon is about 1/6th that on Earth, so the force of gravity on a 180 kg object on the moon would be 1/6th of its weight on Earth. Therefore, the force of gravity on the object would be about 180 kg * 1/6 = 30 kg.


A person holding a 30 kg box 1 m above the floor puts it down. How much work was done Remember the force of an object's weight mass and times gravity.?

The work done to lift the box is given by the formula: work = force x distance. The force here is the weight of the box, which is the mass (30 kg) times the gravitational acceleration (9.8 m/s^2), equal to 294 N. The distance lifted is 1 m. Therefore, the work done to lift the box is 294 J.


What is the weight on earth of a girl with a mass of 30 kg the acceleration due to gravity on earth is 9.8ms?

The weight of the girl on Earth can be calculated using the formula: weight = mass x acceleration due to gravity. Therefore, the weight of the girl would be 30 kg x 9.8 m/s^2 = 294 N.


What 1 3 third of 18 kg?

One third of 18 kg is equal to 6 kg. To find one third of a number, you divide the number by 3. In this case, dividing 18 kg by 3 gives you 6 kg, which is one third of 18 kg.
