What is the gravitational potential energy of a a cat that weighs 20 N standing on a couch that is 0.5 m above the ground?
The gravitational potential energy of the cat can be calculated using the formula: GPE = weight * height. Given that the weight of the cat is 20 N and the height of the couch is 0.5 m, the gravitational potential energy of the cat is 10 J (20 N * 0.5 m).
What is the initial velocity that must be given to a 1kg mass if it is to move to a height of 20m. what is the total energy?
The initial velocity needed can be calculated using the conservation of energy principle. The gravitational potential energy at height 20m is equal to the initial kinetic energy given to the mass. Using the equation for gravitational potential energy (mgh), where m = mass, g = acceleration due to gravity (9.81 m/s²), and h = height (20m), we can calculate the initial velocity. The total energy of the system will be the sum of the initial kinetic energy and the potential energy at height 20m.
A 20 kg mass is held 4 m above the ground What is the approximate potential energy of the mass with respect to the ground?
The approximate potential energy of the mass with respect to the ground is 784 J. This is calculated as potential energy = mass x gravity x height, which is 20 kg x 9.8 m/s^2 x 4 m.
What is the potential energy of a 20-kg rock?
The potential energy of a 20-kg rock depends on its height above the ground and the gravitational acceleration. The potential energy formula is PE = mgh, where m is the mass of the rock (20 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height above the ground.
What is the potential energy of a 20 kg rock placed at the top of a cliff with a height of 100 meters?
The potential energy of the rock can be calculated using the formula: Potential energy = mass * gravity * height. Given the mass of 20 kg, gravitational acceleration as 9.8 m/s^2, and height of 100 meters, the potential energy of the rock would be 20 kg * 9.8 m/s^2 * 100 m = 19600 J.

What is the Potential energy of an object that has 20 kgand at rest 5 m?
20 kilograms and 5 meters? Potential energy = mass * gravitational acceleration * height PE = (20 kilograms )(9.80 m/s2)(5 meters) = 980 Joules of potential energy -----------------------------------------
How much potential work can a 20 KG block do at a height of 10 m?
Potential work = gravitational potential energy = mass x gravity x height = 20 x 9.8 x 10 = 1960 J or 1.96 kJ
Will a toy car go faster if the height of the ramp is raised from 20 cm to 50 cm?
Yes, the toy car will likely go faster if the height of the ramp is raised from 20 cm to 50 cm. This is because the higher the ramp, the more potential energy the car will have at the top of the ramp, which will be converted into kinetic energy as it rolls down. The increase in height will result in a greater velocity for the toy car due to the increased gravitational potential energy.
What is the potential energy of a 20 kg safe on a shelf 0.5 meters above the ground?
The potential energy of the safe can be calculated using the formula: Potential energy = mass x gravitational acceleration x height. Plugging in the values, we get: Potential energy = 20 kg x 9.8 m/s^2 x 0.5 m = 98 Joules. Therefore, the potential energy of the safe is 98 Joules.

Compare the potential energy of a 20 kg rock on the edge of 100 m cliff with that of a 20 kg rock perched on the edge of a 50 m cliff?
The potential energy of the 20 kg rock on the edge of a 100 m cliff is twice as much as the potential energy of the 20 kg rock on the edge of a 50 m cliff. This is because potential energy is directly proportional to the height of the object above the reference point (in this case, the ground).
What is the potential energy of a 20 kg safe sitting on a shelf 05 meters above the ground?
The potential energy of the safe can be calculated using the formula: Potential Energy = mass * gravity * height. Given the values, the potential energy of the safe is 98 J (20 kg * 9.8 m/s^2 * 0.5 m).
If a 20-kg weight is 5 m above the ground and then falls toward the ground how much kinetic energy does the weight have when it is 2 m above the ground?
At 5 m above the ground, the weight's potential energy is given by PE = mgh = 20 kg x 9.8 m/s^2 x 5 m = 980 J. When the weight is 2 m above the ground, its potential energy is now PE = 20 kg x 9.8 m/s^2 x 2 m = 392 J. The difference in potential energy between the two points is the kinetic energy the weight has at 2 m above the ground, which is KE = 980 J - 392 J = 588 J.
