Akiko has a mass of 55kg how much does Akiko weight? Akiko climbs a flight of six steps each 20cm high how much work does she do in climbing the stairs?
work= forcexdistance force=55x10(or 9.8 depending on which gravitational field strength you use) force= 550N work = 550x0.2 work= 110J six steps=110x6=660J
