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).
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.
The mass' approximate potential energy at four meters is 784 joules.
Potential energy is defined as the energy possessed by a body due to its position in the gravitational field. Approximately it will be got by using the expression mgh. m - the mass in kg g-acceleration due to gravity and h - the height above the surface of the earth The other to find the potential energy so precisely is using the expression G Mm/(R+h)2 or replacing GM by gR2 we get mg(R/R+h)2 Any way the details about h is not given. So finding the potential energy will be in complete.
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.

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 -----------------------------------------
Potential work = gravitational potential energy = mass x gravity x height = 20 x 9.8 x 10 = 1960 J or 1.96 kJ
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.
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.

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).
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).
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.
