The work done in raising the backpack can be calculated as the change in potential energy. Using the formula, work = force x distance, we find that the work done is approximately 740 Joules.

How much work is done in raising a 10.0 kg backpack from the floor to a shelf 1.50 m above the floor?

Use the formula for potential energy: potential energy = mgh (mass x gravity x height). If mass is in kilograms, gravity is in m/s2 (the value is abour 9.8), and height is in meters, then the work will be in joules.


How much energy is required to raise a mass of 200kg to a height of 4 m?

Potential energy of the mass referred to the floor level = M g H .At 4 m above the floor, its potential energy will be M g H = (200) (9.8) (4) = 7,840 joules.That's the energy you have to come up with from somewhere in order to hoist the block.


What is the GPE of a 2 kg ball that is m above the floor?

The gravitational potential energy (GPE) of the ball is given by the formula GPE = mgh, where m is the mass of the ball (2 kg), g is the acceleration due to gravity (9.81 m/s^2), and h is the height above the floor. Without the height (h) above the floor provided, we cannot determine the exact GPE of the ball.


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 is the cats gravitational potential energy relative to the floor if the acceleration due to gravity is 9.8 m's 2?

The cat's gravitational potential energy relative to the floor isEp = m.g.hEp = (the cat's mass) x (gravity) x (the height of the cat's center of mass above the floor).Ep [=] Jmass,m [=] kggravity, g = 9.81 m/s2height, h [=] m
