parameters given are :
mass(m)=20kg
height(h)=30m
acceleration due to gravity(g)=9.8m/s squared
But K.E=1/2MV`2 = mgh = 20x9.8x30 =5880 joules or 5.88 kilo-joules.
What else can I help you with?
What describes the amount of energy a moing object has?
The kinetic energy of a moving object is calculated with the formula E = ½ M v ^2. So to calculate the KE of a 1000-kilogram car moving at 20 metres per second (45 mph) the formula works like this: KE = ½ x 1000 x 20^2 Joules = 500 x 400 Joules or 200,000 J.
What is a kinetic energy of an object that has a mass of 20 kilograms and a speed of 2.8 ms?
The kinetic energy of an object is calculated using the formula KE = 0.5 * mass * velocity^2. Substituting the values gives KE = 0.5 * 20 kg * (2.8 m/s)^2 = 78.4 joules. So, the kinetic energy of the object is 78.4 joules.
Kinetic energy of a moving object varies directly with the square of velocity If a car moving at 60mph has kinetic energy 180 units how many units of kinetic energy does the same car have at 20mph?
The kinetic energy of the car varies with the square of its velocity. Therefore, if the car is moving at 20 mph (which is one-third of 60 mph), its kinetic energy would be (1/3)^2 = 1/9 of the original kinetic energy. So, at 20 mph, the car would have 180/9 = 20 units of kinetic energy.
What is the kinetic energy of a 1 kg mass that is moving with a speed of 20 ms?
The kinetic energy of a moving object is given by the formula 1/2 * mass * speed^2. Plugging in the values for the mass (1 kg) and speed (20 m/s), the kinetic energy would be 200 J.
Define kinetic energy in terms of temperature?
The reverse is usually done .... Define temperature in terms of KE. The temperature of a body is proportional the the average Kinetic Energy of the particles (molecules or atoms) that make up the body. Can't be done the other way because a car traveling at 60 miles per hour has Kinetic energy which has nothing to do with temperature. The car doesn't care if is 100 degrees or 20 degrees.
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.
What is the kinetic energy of an object with a mass of 30kg and a velocity of 20 ms?
6,000 J
What is the kinetic energy of an object that has a mass of 20 kilograms and a speed of 2.8ms?
A. 56 j
What is the kinetic energy of an object that has mass if 30 kilograms moves with a velocity of 20 mm?
To get the kinetic energy of an object you need both mass and velocity. As it stands it can't be answered, as "mm" isn't a recognized unit of velocity
What is a kinetic energy of an object that has mass of 20 kilograms and speed of 2.8ms?
78.4 joules at 2.8m/s

The kinetic energy of an object is calculated using the formula KE = 0.5 * mass * velocity^2. Substituting the values gives KE = 0.5 * 20 kg * (2.8 m/s)^2 = 78.4 joules. So, the kinetic energy of the object is 78.4 joules.
What is the kinetic energy of an object that has a mass of 20 kg and a speed of 2 point 8 m per s?
Kinetic Energy = 1/2 m V2 = 1/2 (20) (2.8)2 = 78.4 joules

If an object weighing 90 kilograms and moving with a velocity of 20 meters per second has a kinetic energy of 4500 Joules. what is its kinetic energy when the velocity is 32 meters per second?
Kinetic energy is directly proportional to the square of velocity, so the kinetic energy will increase. If the velocity increases from 20 m/s to 32 m/s, the kinetic energy will increase by a factor of (32/20)^2 = 2.56. Therefore, the kinetic energy will be 4500 Joules * 2.56 = 11520 Joules when the velocity is 32 m/s.
What is the kinetic energy of a 1 kg mass that is moving with a speed of 20 ms?
