A 10 kg rock is pushed off the edge of a bridge 50 meters above the ground. what was the kinetic energy of rock befor it began to fall?
zero
A rock weighing 98 newtons is pushed off the edge of a bridge 50 meters above the ground. What was the kinetic energy of the rock at the midway point of its fall?
2,450 joules
A rock weighing 98 newtons is pushed off the edge of a bridge 50 meters above the ground What was the potential energy of the rock before it began to fall?
Kinetic Energy = 1/2 x Mass x Velocity2 As the velocity while the rock is on the bridge's edge is 0, it does not have any kinetic energy: Therefore the answer is zero.
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?
Calculate the gravitational potential energy between 5 m and 2 m above the ground. If you ignore air resistance, all of that potential energy will be converted to kinetic energy, so that's the answer.
A 5kg object is being lifted to a height of 8 meters and is dropped what is the kinetic energy of the object at 2 m?
After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy.

A cat with a mass of 4.50 kilograms sits on a ledge 0.800 meters above the ground If it jumps to the ground how much kinetic energy will it have just as it reaches the ground?
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.
If you have a 2kg pendulum bob that is 6 meters above the ground at its high point and 1 meter at its low point how can you figure the kinetic energy?
Calculate the potential energy at its highest point. Don't use the 6 meters above the ground - use the 5 meter difference from the lowest point. This part of the potential energy gets converted into kinetic energy, when the pendulum is at its lowest point. Just assume that all the potential energy (for the 5 meters difference) get converted into kinetic energy.Calculate the potential energy at its highest point.

After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy.

A flowerpot falls from a ledge 50 m above the ground. compare the potential and kinetic energy when it is at 25 m above the ground to its original potential and kinetic energy?
After falling 25 meters, it has less potential energy, by an amount calculated with the formula mgh (mass x gravity x height). If you ignore air resistance, the kinetic energy will increase by the same amount.
Is a flower pot weighing 3 newtons sitting on a windowsill 30 meters from the ground potential or kinetic?
Potential Energy The object is not in movement.
What is the mathmetical formula for kinetic energy?
Kinetic Energy = 1/2(mass in kilograms)(meters per second)2
What is the kinetic energy of a 200kg boulder when it is 1000m above the ground?
Kinetic energy = 1/2 (mass) (speed)2 = 1/2 (0.2) (200)2 = 4,000 joules
What is the energy of a system by virtue of its motion?
That's called kinetic energy. The formula is: Kinetic energy = (1/2) x mass x velocity2. If mass is in kilograms, and velocity (or speed, really) in meters per second, the energy will be in Joules.
