GPE = mgh = 4 x 9.8 x 3 = 117.6J
Ep is potential energy of a mass, m ,in gravity field, g ,at height of h above a reference ground
Momentum = (mass) x (speed) = 7,500 poundmass-miles per hourAfter laboriously converting all of that to metric units for you ... at noextra cost ... we find that the momentum is equivalent to1,520.8 kilogram-meters/second
times it together
Mass = Density x Volume
Pressure=mass/unit area
How do you calculate the mass of an object that has a potential energy of 180 joules and rest at the top of a hill 15 meters from the ground?
Just use the formula for gravitational potential energy:GPE = mgh (mass x gravity x height) Gravity is about 9.8 meters/second squared. Since all units are SI, the answer will be in joules.
If a cat that has a mass of 4.50 kilograms sits on a ledge that is 0.800 meters above ground and it jumps down to the ground, it will have a specific amount of kinetic energy just as it reaches the ground. In this instance, the answer would be 35.3J.
The potential energy, expressed in joules, is 196 times its height above ground, expressed in meters.
The book has a mass of 0.46kg
A large book has more mass, which requires more force to be moved.
A large book has more mass, which requires more force to be moved.
Use the formula potential energy = mgh (mass x gravity x height), mass in kilograms, gravity about 9.8 (meters per square second), height in meters. Answer will be in Joules.
You can't measure mass in meters. Meters is a measure of length, not mass
(4 x 5) kilogram-meters = 20 joules
The book's potential energy is 294 joules.
The mass' approximate potential energy at four meters is 784 joules.
