1.	how fast must a 58 kg mountaineer climb a hill that has a slope of 16° to come up with a power output pf 1.0 hp?
Answer» ong>1 hp = 746 watts = 746 N-m/s Going up a 16 degree hill, *H = DISTANCE sin 16 WORK = mgh POWER = W/time = mgh/t = mg distance * sin 16 /time Power = mg * sin16 * distance/time Power = mg * sin16 * speed Speed = Power / (mg sin16) Speed = 746 / (58* 9.8 * sin 16) = 4.76m/s**

Answer»

ong>1 hp = 746 watts = 746 N-m/s

Going up a 16 degree hill,

H = DISTANCE * sin 16

WORK = mgh

POWER = W/time = mgh/t = mg distance * sin 16 /time

Power = mg * sin16 * distance/time

Power = mg * sin16 * speed

Speed = Power / (mg sin16)

Speed = 746 / (58* 9.8 * sin 16) = 4.76m/s
