A CHAMPION ATHLETE CAN PRODUCE ONE HORSEPOWER(746 W) FOR A SHORT PERIOD OF TIME. THE NUMBER OF STEPS 16 CM HIGH STEPS A 70 KG ATHLETE COULD ASCEND IN ONE MINTUE WHILE EXPENDING ONE HORSEPOWER IS?tHE COORRCT ANSWER IS=408.
THIS IS WHAT I TRIED I COULD NOT GET 408
W=WG=MGH
P=W/T=MGH/T
G=9.8M/S
P=746 W
H=16cm
M=70KG
746=W=70KG*9.8*16=10796/746=14.7
HOW DO I GET 408 WHAT DID I GO WRONG????
