How high up is a 3 kg objectthat has 300 joules of energy?
Use the formula for gravitational potential energy (PE=mgh), and solve for height.
What is the potential energy of a 10.2 kg rock that is sitting on top of a hill that is 300 meters high?
P.E=mgh =10.2 by 10 by 300 P.E=30,600J
What is the potential energy of a ten kg rock that is sitting on a hill that is 300 meters high?
The rock's PE is 29400 joules.
What effect does gravity have on the mass of an object?
Gravity has no effect on the mass of an object. However, an object's weight is the measurement of gravitational force on the object. The gravitational force on the moon for example is ~ 1/6 of that on Earth. A 300 kg object would weigh 3000N (Newtons) on the Earth but only weigh 500 N on the Moon but its mass would still be 300 kg on the Moon and on the Earth.
What is the potential energy of a 5 kg object sitting on a shelf 3 m high?
PE = m x 9.8 x h:So, 5kg x 9.8 x 5m = 245 joules potential energy.

What is the potential energy of an object that has a mass of 40 kg at a height of 17 meters?
The object's potential energy is 6,664 joules.
What is the kinetic energy of an object that has a mass of 20 kg and a speed of 2.8m per second?
The object's kinetic energy is 78.4 joules.

1000 kg moving 1 m s or 70 kg at 8 m s?
If the question is analyzed by a non-relastivistic approach of the kinetic energy due to the relatively low velocity of the objects, the equation is: K = 0.5mv² where: K: kinetic energy (Joules) m: mass of the object (kg) v: velocity of the object (m/s) The kinetic energy of object 1 at 1000 kg and 1 m/s is: K1 = 0.5(1000kg)(1m/s)² = 500 kg-m/2 = 500 J The kinetic energy of object 2 at 70 kg and 8 m/s is: K2 = 0.5(70kg)(8m/s)² = 2240 J If higher energy is preferable, than select object 2. If lower energy is preferable, than select object1.
What happens if you place a 0.5 kg object in a 15 L tub of water and 300 ml is displaced?
It sinks. (the object weighs more than the water displaced.)
Determine the potential energy of an object resting at 854 meters and has a mass of 17.8 kg?
The potential energy of any object is measured using the equation U = mass * gravity * height to the object. Thusly: U = m*G*h U = 17.8 kg * 9.81 m/s2 * 854 m U = 149 123.8 kg m2/s2 or Joules
Suppose object A (2 kg) is at rest and object B (10 kg) runs into it with high speed. What is the likely result?
Object A will move in the direction of object B's velocity; object B will continue in that direction with a final speed less than its initial speed. (Apex)
What is 300 g and 2.5 kilogram in kilogram?
300 g = 0.3 kg 2.5 kg = 2.5 kg
