Work = (force) x (distance) = m g H = (90) x (9.807) x (6) = 5,295.78 joules
Power = work/time = 5,295.78/3 = 1,765.26 watts = 2.366 horsepower
A physically impossible feat, but the math is bullet-proof.

David drops a ball from a bridge at an initial height of 70 meters what is the height of the ball to the nearest tenth of a meter exactly 2 seconds after he releases the ball?
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
Which is faster 50 meters in 10 seconds or 30 meters in 5 seconds?
50 meters in 10 seconds is faster. you go 5 meters per second in 50 meters per second, and you go 6 meters a second in 5 seconds..
How much work is done when a 70kg person climbs a ladder meters tall?
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.
What is the height of ladder which is leaning at 60 degree from the wall and separated with a distance of 4.2cm from the wall?
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.

How much energy is needed in Joules for a 90 kg woman was to climb a ladder 6 meters in height?
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.
