You weigh 177lb on Earth (4.448 N = 1 lb). When you reach Alderon, you discover that its gravity is 1.5 that of earth.What is your weight on...

177 lb of weight of man on earth = 177*4.448N=787.296N, as it is known that 1lb weigt = 4.448 Newton.

Therefore the mass of the man on the earth = (787.296/g)Kg, where g is the acceleration due to gravity on earth.

Therefore on Alderon , the weight of the man = mass* acceleration due to gravity on Alderon=

=(787.296*/g)kg * (g'), where g' is the acceleraton due to gravity on Alederon = 1.5times earth gravity =1.5g

Weight on Alderon=(787.296/g)kg * (1.5g)=1180.944 N
