Work = 500 x 3 = 1,500 joules
Power = (work/time) = 1,500/5 = 300 watts = about 0.4 horsepower (rounded)

What is the origin for the word ladder that you climb?
Old English hlǣdder; related to Old High German leitara, meaning steps.
Two people who weigh the same clim a flight of stairs in 30's while the second person climbs in 40's which person does more work?
The amount of work done by each person can be calculated by analyzing the amount of energy they each use to climb the stairs. Energy is related to work (force multiplied by distance) and can be measured in joules. The person who climbs the stairs in 30 seconds will have used more energy (and thus done more work) than the person who climbs the stairs in 40 seconds. This is because the person who climbs in 30 seconds had to exert more force to climb the stairs faster thus expending more energy in a shorter amount of time.The following factors will determine how much work each person did: The weight of each person The amount of stairs climbed The rate of ascent (how fast they climbed the stairs) The amount of energy usedAlthough the two people weigh the same the person who climbed the stairs in 30 seconds used more energy than the person who climbed in 40 seconds. This is because the person who climbed in 30 seconds had to exert more force in order to ascend the stairs faster. This force requires more energy to be used and thus the person who climbed in 30 seconds did more work.
How much power is required for a 100 kg woman to climb a ladder 10 meters in height in 10 seconds?
When she reaches the top of the ladder, her potential energy has increased byM G H = (100) (9.8) (10) = 9,800 joules.Spread over 10 seconds, her potential energy increases at the rate of 980 watts.She has to work at at least that rate plus more, since muscular activity is never 100% efficient.By the way, this is a very fast climb. It might not be obvious from any of the numbersdiscussed so far. But consider that 980 watts is 1.32 horsepower, which is a mightyeffort for any human being. Of course, being a 100-kg (220-lb) woman, she may wellbe accustomed to it.
How much power is required in watts for a 90kg woman to climb a ladder 6 meters in height in 3 seconds?
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.
When A baseball is hit straight up at an initial velocity of 100 ms how long will it take to hit the ground?
The baseball will travel upwards until its velocity is zero and then fall back down again. The acceleration of the baseball is the constant acceleration due to gravity acting in a downwards direction. The time taken to fall back down will be the same as the time to climb, thus the total time is twice the climb time. Use Netwon's equations of motion and ignore air resistance, the time to the top of the climb is: v = u + at → t = v - u/a v = final velocity = 0 m/s at the top of the climb u = initial velocity = +100 m/s a = acceleration = -g m/s² t_top = 0 - (100 m/s) / (-g m/s²) = 100/g s → t_total = 2 × t_top = 2 × 100/g s = 200/g s ≈ 200/9.81 s ≈ 20.4 s
