If my weight is 53.18 kg and i walked up a flight of stairs 4.3 meters tall in 11.35 seconds what would be the work it took me to climb up the stairs in joules?

2200 J

Explanation:

Work = force × distance

W = mg h

W = (53.18 kg) (9.8 m/s²) (4.3 m)

W ≈ 2200 J

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
