Work = (force) x (distance) = m g H = (90) x (9.807) x (6) = 5,295.78 joulesPower = work/time = 5,295.78/3 = 1,765.26 watts = 2.366 horsepowerA physically impossible feat, but the math is bullet-proof.
5 meters
approx. 50 seconds
19.6 meters / 64.4 ft
Distance of fall in T seconds = 1/2 g T2Distance of fall in 2 seconds = (1/2) (9.8) (2)2 = (4.9 x 4) = 19.6 metersHeight of this particular ball after 2 seconds = (70 - 19.6) = 50.4 meters
The work done by a 70kg person climbing a ladder depends on the height of the ladder, but can be calculated using the formula work = force x distance. The force is the person's weight (70kg x 9.8m/s^2) and the distance is the height of the ladder.
cos60=4.2cm/x x=4.2cm/cos60 x=8.4cm Therefore the height of the ladder is 8.4cm. However, i think you mean meters because that is a very tiny ladder lol.
15 meters, or less, depending on the angle.

A 22-foot ladder is equivalent to approximately 6.7 meters.

The time required for a stone to fall from a given height can be calculated mathematically. Time equals the square root of two times the distance divided by force of gravity. Time is in seconds, distance in meters, and the force of gravity on Earth is 9.8 meters/second ^2.
Distance of fall in T seconds = 1/2 g T2Distance of fall in 2 seconds = (1/2) (9.8) (2)2 = (4.9 x 4) = 19.6 metersHeight of this particular ball after 2 seconds = (70 - 19.6) = 50.4 meters
The energy needed to climb a ladder can be calculated using the formula: potential energy = mass x gravity x height. Plugging in the values for the woman's mass (90 kg), height (6 meters), and the acceleration due to gravity (9.81 m/s^2), the energy required would be approximately 5294.2 Joules.
