Question

BASIC SCIENCE. A BOY OF MASS 50KG RUNS UP A FLIGHT OF 10 STAIRS EACH OF HEIGHT 0.2M IN 5 SECONDS CALCULATE HIS POWER.

Answer 1

force = mass * g
work = force * distance
power = work/time

Answer 2

I think your school subject is physics.

Answer 3

power=work /time.p=mgh=50*0.2*50/5=100

Answer 4

Total height runned=10*0.2=2.work done=mgh=50*10*2.time taken=5sec.power =work/time=50*10*2/5=200joules.

Answer 5

100% CORRECT
