How much work did he do weight lifting 2500 n from the floor to over his head a point 2 m above the ground?
The work done lifting the weight is given by the formula: W = Fdcos(theta), where F is the force (2500 N), d is the distance (2 m), and theta is the angle between the force and the direction of motion (0 degrees for lifting straight up). So, the work done is 2500 N * 2 m = 5000 Joules.

A ball held above the floor has what type of energy?
Any object above ground level has gravitational potential energy. Actually, ground level is commonly chosen as the reference level, but any other level may be chosen as well. The choice is arbitrary.
Is noise louder on the top floor or first floor?
Noise is typically louder on the first floor since it is closer to ground-level activities like street traffic and pedestrians. The top floor may have less external noise but more internal noise from neighbors above.
What are 5 examples of pulling forces?
Tugging a rope during a game of tug-of-war. Lifting an object from the ground. Dragging a heavy piece of furniture across the floor. Pulling a door open. Stretching a rubber band.
How much force does a floor exert on you?
The force a floor exerts on you is equal and opposite to your weight. This force is known as the normal force, which supports your weight and prevents you from falling through the floor. The magnitude of this force depends on your mass and the acceleration due to gravity.
What is the energy conversion of a falling bag hitting the floor?
When a falling bag hits the floor, the potential energy of the bag due to its height above the ground is converted into kinetic energy as it falls. Upon impact with the floor, some of this kinetic energy is dissipated as sound and heat energy.
Why is the 1st floor above the ground floor in the United Kingdom?
The ground floor is at ground level so the floor immediately above it must be the first floor.
What are male and female weight limits for lifting from floor?
over 9000
How do you call the floor above cellar?

What is 'first floor' in British English?
What in America is called the 'first floor' is called the 'ground floor' in Britain. The floor immediately above that is the 'first floor', what Americans would call the 'second floor'.
What is integer to represent 40 floors above ground level?
To represent 40 floors above ground level with an integer, you would simply use the number 40. This integer indicates the specific floor number above the ground level, which is typically considered floor 0 or floor 1, depending on the building's numbering system. Thus, 40 directly corresponds to the 40th floor above ground.
What is the difference between first floor from ground floor?
Actually, there is not much difference, but a ground floor is usually the very bottom one and the first floor is usually the one above
